Algae Classification Quiz

Male Gamete Transfer

• The structure responsible for transferring male gametes to the archegonium is the pollen tube.

Gymnosperms

• Gymnosperms are referred to as "naked seed" plants because their seeds remain exposed after fertilization.
• They are also described as having ovules that are not enclosed by any ovary wall.

Spores

• Microspores and megaspores are produced in the sporangia.

Cones

• Male cones are formed by microsporophylls, while female cones are formed by megasporophylls.

Zygote Development

• After fertilization, the zygote develops into an embryo.

Angiosperms Classification

• Angiosperms are divided into two classes: monocots and dicots.

Pollen Tube Function

• The primary function of the pollen tube is to facilitate the transfer of sperm cells to the ovule for fertilization.

Zygote Formation

• The zygote is formed in the archegonium after fertilization occurs.

Algae Characteristics

• A characteristic of algae includes their ability to perform photosynthesis and live in aquatic environments.

Algae Classification

• Algae are classified into three main classes based on pigment and stored food: green algae (Chlorophyta), brown algae (Phaeophyceae), and red algae (Rhodophyta).

Algae Reproduction

• Algae typically reproduce vegetatively through fragmentation or asexual reproduction methods like binary fission.

Bryophyte Structure

• The main plant body of a bryophyte is called the gametophyte.
• Male sex organs in a bryophyte are called antheridia, while female sex organs are referred to as archegonia.

Pteridophyte Structure

• The main plant body of a pteridophyte is called the sporophyte.
• Pteridophytes produce reproductive structures known as sporangia.

Gametophyte Habitat

• Gametophytes of pteridophytes prefer to grow in moist environments.

Plant Types

• Gymnosperms and angiosperms are classified as seed-producing plants.
