When you look at a pine tree the plant you see is?

When you look at a pine tree the plant you see is?

Pine trees are conifers (coniferous = cone bearing) and carry both male and female sporophylls on the same mature sporophyte. Therefore they are monoecious plants. Like all gymnosperms pines are heterosporous and generate two different types of spores (male microspores and female megaspores).

Are maple leaves diploid?

Maples generally are diploids with two copies of 13 base chromosomes (2n = 2x = 26).

What is the conspicuous part of a fern plant?

leaf The most conspicuous part of the fern sporophyte is the leaf. The typical fern leaf, often termed a frond, is an elaborate structure composed of numerous leaflets.

What is endosperm quizlet?

Endosperm. Is a tissue produced inside the seeds of most of the flowering plants around the time of fertilization. It surrounds the embryo and provides nutrition in the form of starch, though it can also contain oils and protein. Primary endosperm nucleus. Results from the fusion of the male.

Are pine cones gametophytes?

Cones form on a mature sporophyte plant. Inside male cones, male spores develop into male gametophytes. Each male gametophyte consists of several cells enclosed within a grain of pollen. Inside female cones, female spores develop into female gametophytes.

Is a pine a gymnosperm?

Conifers. Conifers like the spruce, cedar and pine tree are gymnosperms and have seeds on cones.

How many chromosomes do maple trees have?

maples have 26 chromosomes and the hy- brids produce apparently normal viable seeds.

Are pollen grains haploid or diploid?

haploid Pollens are haploid as a result of meiosis. Pollen grain are male gametes in plants. And gametes are haploid in order to restore the correct number of chromosomes in the zygote after fusion . For that the mother cell undergo meiosis to produce four haploid cells.

What is a fern plant?

Ferns are plants that do not have flowers. Ferns generally reproduce by producing spores. Similar to flowering plants, ferns have roots, stems and leaves.

What is a fern leaf called?

The leaves of ferns are often called fronds. Fronds are usually composed of a leafy blade and petiole (leaf stalk). Leaf shape, size, texture and degree of complexity vary considerably from species to species. A fern leaf or frond. Parts of a fern leaf.

Are structures within the ovaries of flowers inside which female gametophytes develop?

Female gametophytes of flowering plants develop within the ovule (megaspore) contained within an ovary at the base of the pistil of the flower.

Which of the following is not a type of primary meristematic cell found in apical meristems view available hint?

Which of the following is not a type of primary meristematic cell found in apical meristems? The vascular cambium is a type of cell found in lateral (not apical) meristems and is involved in secondary (not primary) growth.

Is a pine tree a sporophyte or gametophyte?

Pine tree is a gymnosperm. Sporophyte is the dominant phase in the life cycle of gymnosperms.

Are maple trees gymnosperms?

Broadleaf species such as oak, hickory, ash, maple, walnut, etc. are angiosperms. Needle-leaf species such as pine, spruce, fir, hemlock, baldcypress, larch, etc. are gymnosperms.

Is maple a gymnosperm?

Broadleaf species such as oak, hickory, ash, maple, walnut, etc. are angiosperms. Needle-leaf species such as pine, spruce, fir, hemlock, baldcypress, larch, etc. are gymnosperms.

Is a maple tree an angiosperm or gymnosperm?

Angiosperms are trees have broad leaves that usually change color and die every autumn. Oaks, maples and dogwoods are examples of deciduous trees. Some angiosperms that hold their leaves include rhododendron, live oak, and sweetbay magnolia.

How many chromosomes are in a pine tree?

12 chromosomes Like all other species of Pinus, the haploid genome of Pinus strobus consists of 12 chromosomes and its diploid genome has 24 chromosomes.

Where do silver maple trees grow?

Silver maples grow best in temperate northern and mid-southern climates in the U.S. and Canada. This tree reaches a height of 50–80 feet, with a spread of 35–50 feet when fully grown.

What are diploid plants?

In sporophyte. In the sporophyte phase a diploid (having two sets of chromosomes) plant body grows and eventually produces spores through meiosis. These spores divide mitotically to produce haploid (having a single set of chromosomes) gamete-producing bodies called gametophytes.

How do you know if a plant is haploid or diploid?

Parts of the plant, such as leaves or stems, produce roots and become an independent plant. male cells in the pollen grain with female cells in the ovule. Haploid: having a single set of chromosomes in each cell. Diploid: having two sets of chromosomes in each cell, one set from each parent.

Is a fern a leaf?

The leaves of ferns are often called fronds. Fronds are usually composed of a leafy blade and petiole (leaf stalk). Leaf shape, size, texture and degree of complexity vary considerably from species to species. A fern leaf or frond.

Are ferns gymnosperms?

Ferns are vascular plants differing from lycophytes by having true leaves (megaphylls), which are often pinnate. They differ from seed plants (gymnosperms and angiosperms) in reproducing by means of spores and they lack flowers and seeds.

What are fern plants?

Ferns are plants that do not have flowers. Ferns generally reproduce by producing spores. Similar to flowering plants, ferns have roots, stems and leaves.

What is the frond of a tree?

The leaf-like structures of a fern are known as fronds. The term “frond” is used in several different ways. Most commonly, when someone talks about a frond, he or she means a pinnately compound leaf or leaf-like structure on a plant, such as the fronds of a palm tree.

Are flowers gametophyte or sporophyte?

In flowering plants, the gametophyte generation takes place in a flower, which forms on the mature sporophyte plant. Each male gametophyte is just a few cells inside a grain of pollen. Each female gametophyte produces an egg inside an ovule. Pollination must occur for fertilization to take place.

Where would you find a male gametophyte in a flowering plant describe its shape and structures?

Male Gametophyte (The Pollen Grain) The microsporangia, which are usually bi-lobed, are pollen sacs in which the microspores develop into pollen grains. These are found in the anther, which is at the end of the stamen—the long filament that supports the anther.

In which of the following structures of a plant are apical meristems found?

The apical meristem, also known as the “growing tip,” is an undifferentiated meristematic tissue found in the buds and growing tips of roots in plants.

In which of the following structures of a plant or apical meristems found?

Meristems are classified by their location in the plant as apical (located at root and shoot tips), lateral (in the vascular and cork cambia), and intercalary (at internodes, or stem regions between the places at which leaves attach, and leaf bases, especially of certain monocotyledons—e.g., grasses).

Are pine trees gametophytes?

The gametophytes of conifers, like those of other seed plants, live out their brief, nonphotosynthetic lives almost entirely within the spore wall. All of their nutrition is derived from the parent sporophyte. The female gametophyte is never released from the tree until the seed matures.

Are pines gymnosperms?

Conifers. Conifers like the spruce, cedar and pine tree are gymnosperms and have seeds on cones. Most coniferous trees are evergreen and are specially adapted to survive in areas with lots of snow.
