What is a fern gametophyte?
The fern gametophyte is a small plant that exists as a prolonged intermediate in the fern life cycle, between the germination of a spore and the mature sporophyte. Following its emergence from a spore, it grows from two cells into a distinctively shaped structure containing several hundred cells.
Where would you find a fern gametophyte quizlet?
Fern sperm use flagella to swim through moisture to fertilize the egg. The small heart-shaped gametophyte grows on or just below the soil level in moist areas. Among living vascular plants, however, the sporophyte (diploid) generation is the larger and more complex plant in the alternation of generations.
What structure functions both in support of the plant and transport of water and nutrients in Tracheophytes?
Vascular plants (tracheophytes) differ from the nonvascular bryophytes in that they possess specialized supporting and water-conducting tissue, called xylem, and food-conducting tissue, called phloem.
Which of the following is a trait that involved in all land plants?
All land plants share the following characteristics: alternation of generations, with the haploid plant called a gametophyte and the diploid plant called a sporophyte; formation of haploid spores in a sporangium; and formation of gametes in a gametangium.
Where does the sporophyte grow and receive nutrients Brainly?
The sporophyte is not free-living in bryophytes. It is attached to the gametophyte and receives nutrients from it.
What is a moss sporophyte?
Moss sporophytes A moss sporophyte consists of a spore-containing capsule, possibly sitting atop a stalk (called a seta). In this photograph. you can see many brownish sporophytes (the stalked spore capsules) that have grown from the greenish, leafy-stemmed gametophyte.
What would happen to a moss sporophyte is the gametophyte that produced it died explain your answer?
The sporophyte quickly becomes independent and when this happens the gametophyte typically dies. The sporangia release spores produced via meiosis ad once the spores germinate the cycle happens all over again.
What is the role of the gametophyte in ferns quizlet?
What is the role of the gametophyte in ferns? produce gametes and protect the developing zygote. Plant tissue consisting of cells joined into tubes that transport water and nutrients throughout the plant body.
What structures are involved in the uptake and transport of nutrients and water in vascular plants?
The structure of plant roots, stems, and leaves facilitates the transport of water, nutrients, and photosynthates throughout the plant. The phloem and xylem are the main tissues responsible for this movement.
What is xylem and phloem?
The vascular system is comprised of two main types of tissue: the xylem and the phloem. The xylem distributes water and dissolved minerals upward through the plant, from the roots to the leaves. The phloem carries food downward from the leaves to the roots.
What adaptations help plants live on land?
Plants have evolved several adaptations to life on land, including embryo retention, a cuticle, stomata, and vascular tissue.
What adaptations do plants have that allow them to survive on land quizlet?
One of the adaptations for land plants was a cuticle. A cuticle is a waxy covering of the epidermis that does not allow water to be lost. Another adaptation is vascular tissue. The vascular tissue allows the transportation of sugar and water through the entire plant.
How does the sporophyte obtain its water and nutrients?
How does the sporophyte obtain nutrients? In general, the bryophyte sporophyte is a long, tiny stem that grows on the top of the gametophyte. The sporophyte depends complelety on the gametophyte to obtain nutrients.
Where the sporophyte grow and receive nutrients?
The sporophyte is not free-living in bryophytes. It is attached to the gametophyte and receives nutrients from it.
Can you eat moss?
Yes, moss is edible so you can eat moss. However, its nutrient value is limited, it is unpleasant in taste but can be prepared and eaten in a survival scenario. Some animals have moss in their diet.
How do moss carry out gas exchange?
When the moss leaves are wet their entire surface is covered by a film of water. Gas exchange cannot happen through the water, but the snorkels stick out above the water and are dry at the tips to allow for gas exchange.
What does sporophyte generation produce that can grow to form the next gametophyte generation?
haploid spores Meiosis within the capsule of the sporophyte yields haploid spores that are released and eventually germinate to form a male or female gametophyte.
Which process is required for a plant to transition from the gametophyte to sporophyte life stage?
A haploid spore germinates and begins to divide by mitosis to form the small multicellular gametophyte stage. The gametophyte stage produces gametes (by mitosis) which fuse to form a zygote. The zygote divides by mitosis to form the large multicellular sporophyte stage.
What is the main structure of the gametophyte in the fern life cycle?
While the sporophyte consisted of fronds and rhizomes, the gametophyte has leaflets and rhizoids. Within the gametophyte, sperm is produced within a structure called an antheridium. The egg is produced within a similar structure called an archegonium.
What do the moss life cycle and the fern life cycle have in common quizlet?
What do the moss life cycle and the fern life cycle have in common? Fertilization produces a diploid cell. In a plant's life cycle, how many sporophyte generations occur between one gametophyte generation and the next time that eggs and sperm are produced?
How does a plant take in carbon dioxide?
Carbon dioxide is a gas found in the air; plants can take in this gas through tiny holes in their leaves. Once they have water and carbon dioxide, they can use energy from sunlight to make their food.
How does carbon dioxide enter the plant?
Carbon dioxide enters through tiny holes in a plant's leaves, flowers, branches, stems, and roots. Plants also require water to make their food. Depending on the environment, a plant's access to water will vary.
What is the function xylem?
Xylem is the specialised tissue of vascular plants that transports water and nutrients from the plant–soil interface to stems and leaves, and provides mechanical support and storage. The water-conducting function of xylem is one of the major distinguishing features of vascular plants.
What do stomata do?
Through photosynthesis, they use sunlight and carbon dioxide to make food, belching out the oxygen that we breathe as a byproduct. This evolutionary innovation is so central to plant identity that nearly all land plants use the same pores — called stomata — to take in carbon dioxide and release oxygen.
What anatomical structures lead to the adaptation of plants to land?
Their major adaptions to life on land include a waxy cuticle and root-like structures (rhizoids).
Which of the following adaptations allow plants to live successfully on land?
Four major adaptations are found in all terrestrial plants: the alternation of generations, a sporangium in which the spores are formed, a gametangium that produces haploid cells, and apical meristem tissue in roots and shoots.
What are three adaptations that help plants survive on land?
Plants have evolved several adaptations to life on land, including embryo retention, a cuticle, stomata, and vascular tissue.
What is the role of the sporophyte?
Sporophyte is the diploid phase in the life cycle of a plant. It produces spores by meiosis that give rise to haploid gametophytes.
How does the sporophyte obtain nutrients?
The sporophyte is not photosynthetic. Thus both the embryo and the mature sporophyte are nourished by the gametophyte. Meiosis within the capsule of the sporophyte yields haploid spores that are released and eventually germinate to form a male or female gametophyte.
What is sporophyte in plants?
Definition of sporophyte : the diploid multicellular individual or generation of a plant with alternation of generations that begins from a diploid zygote and produces haploid spores by meiotic division — compare gametophyte.
