Vascular tissue: Responsible for transport, consisting of xylem (water transport)

2.

and phloem (food transport).

Ground tissue: Includes parenchyma, collenchyma, and sclerenchyma, which

3.

provide support, storage, and photosynthesis.

Understanding these tissues helps explain how plants grow, transport nutrients, and

defend themselves.

How Do Plants Reproduce?

Plants reproduce through two main methods: sexual and asexual reproduction.

Sexual reproduction: Involves the fusion of male (pollen) and female (ovule)

1.

gametes, leading to seed formation. This process increases genetic diversity.

Asexual reproduction: Also called vegetative propagation, where new plants grow

2.

from parts of the parent plant such as stems, roots, or leaves, producing clones.

Examples of asexual reproduction include runners in strawberry plants and tubers in

potatoes.

What Role Do Plant Hormones Play?

Plant hormones, or phytohormones, regulate growth, development, and responses to

stimuli. The main types include:

Auxins: Promote cell elongation and root initiation.
