Plant Groups and Reproduction

What are the principal reproductive structures of angiosperms?

How do bryophytes anchor themselves to the ground?

What is the primary method of reproduction in pteridophytes?

What is a disadvantage of asexual reproduction in plants?

What distinguishes gymnosperms in terms of seed protection?

Identify one advantage of sexual reproduction over asexual reproduction.

What type of vascular tissue do gymnosperms and angiosperms possess?

What is the role of pollinating agents in sexual reproduction?

How does vegetative reproduction benefit plants?

Describe one method by which plants perform asexual reproduction.

Plant Groups

Bryophytes have no vascular tissues (xylem and phloem), lack true roots and stems.
Pteridophytes have true roots, an underground stem and large leaves. They have well-developed vascular tissues (xylem and phloem).
Gymnosperms have true roots and woody stems. They have true roots, a tap root system, with lateral roots and small needle-shaped leaves.
Angiosperms have true roots, stems and leaves. They have well-developed vascular tissues (xylem and phloem).

Reproduction in Plants

Asexual reproduction involves a single parent.
Sexual reproduction involves the fusion of gametes from two parents.

Asexual Reproduction

Advantages
- Produce many offspring quickly
- Requires less energy
- Offspring are identical to the parent
- Does not rely on pollinators or dispersal agents
Disadvantages
- No genetic variation
- All offspring are susceptible to the same environmental pressures
- Weak characteristics are passed on

Sexual Reproduction

Advantages
- Offspring are genetically diverse
- Reduces the chances of inheriting disease
- Farmers can select for desirable traits
Disadvantages
- Takes longer than asexual reproduction
- Fewer offspring
- Requires more energy
- Relies on pollinators

Flowers as Reproductive Organs

Flowers are the reproductive organs of angiosperms.
