Biology Chapter 30 Plant Diversity

Which of the following contains multiple gymnosperm ovules?

Which of the following is found inside a pollen grain?

What are the main components of a mature gymnosperm seed?

The gametophyte generation is?

The sporophyte generation is?

After fertilization of the ovule, the _______ develops into the food supply of the mature seed.

After fertilization of the ovule, the _______ develops into the seed coat.

After fertilization of the ovule, the ________ develops into the embryo of the mature seed.

Ovules are housed within?

The male gametophytes of flowering plants are also referred to as _____?

Which of these is unique to flowering plants?

In flowering plants the integuments of the ovule develop into a(n) _____?

A carpel is composed of _____?

A stamen consists of _____?

In angiosperms, pollination is the transfer of pollen grain to the _____ of a flower on the same plant or another plant of the same species.

Gymnosperm Reproductive Structures

Ovulate cones contain multiple ovules and mature into gymnosperm cones once ovules become seeds.
The male gametophyte is housed within pollen grains, initiating fertilization upon pollination of the ovule.

Seed Structure and Development

Mature gymnosperm seeds comprise an embryo, seed coat, and food supply, providing nourishment and protection for the sporophyte generation.
The embryo and sporophyte generation are both diploid, while the gametophyte generation is haploid.

Reproductive Cells

The megaspore is a haploid structure that develops into the food supply after fertilization.
The integument, surrounding the ovule, transforms into the seed coat post-fertilization.
The fertilized egg, after ovule fertilization, evolves into the embryo of the mature seed.

Flowering Plant Features

Ovules are located within ovaries.
Male gametophytes in flowering plants are referred to as pollen grains.
Double fertilization is a process unique to flowering plants, where two sperm nuclei fertilize different cells.

Floral Structures

The integuments of the ovule give rise to the seed coat in flowering plants.
A carpel is made up of the stigma, style, and ovary.
A stamen consists of an anther and filament, contributing to pollen production.

Pollination Process

In angiosperms, pollination occurs when pollen grains are transferred to the stigma of a flower, which can be on the same or a different plant of the same species.
