Study Notes
Overview of Plant Parts
- Plants are comprised of several organs that work together to carry out essential functions.
- These organs can be classified into two main categories: vegetative and reproductive organs.
Vegetative Organs
-
Roots
- Found underground
- Anchor the plant and absorb water and nutrients from the soil
- Types: taproot (carrot), fibrous root (grass), and adventitious root (potato)
-
Stem
- Connects the roots to the leaves
- Provides support and allows for transportation of water, nutrients, and sugars
- Types: herbaceous (non-woody) and woody (tree-like)
-
Leaves
- Carry out photosynthesis
- Consist of blade (flat part), petiole (stem), and veins (vascular tissue)
Reproductive Organs
-
Flower
- Responsible for reproduction
- Consists of sepals (protective), petals (attractive), stamen (male), and carpels (female)
-
Fruit
- Develops from the ovary of a flower
- Contains seeds and protects them until germination
- Types: simple (e.g., banana), aggregate (e.g., raspberry), and composite (e.g., pineapple)
-
Seed
- Embryo of a new plant
- Consists of seed coat, endosperm (food source), and embryo (radicle and cotyledon)
Plant Structure
- Plants consist of vegetative and reproductive organs that work together to perform essential functions.
Vegetative Organs
-
Roots
- Found underground, anchoring the plant and absorbing water and nutrients from the soil.
- Types: taproot (e.g., carrot), fibrous root (e.g., grass), and adventitious root (e.g., potato).
-
Stem
- Connects roots to leaves, providing support and facilitating transportation of water, nutrients, and sugars.
- Types: herbaceous (non-woody) and woody (tree-like).
-
Leaves
- Perform photosynthesis, responsible for plant growth and development.
- Consist of blade (flat part), petiole (stem), and veins (vascular tissue).
Reproductive Organs
-
Flowers
- Responsible for plant reproduction.
- Consist of sepals (protective), petals (attractive), stamen (male), and carpels (female).
-
Fruits
- Develop from the ovary of a flower.
- Contain seeds and protect them until germination.
- Types: simple (e.g., banana), aggregate (e.g., raspberry), and composite (e.g., pineapple).
-
Seeds
- Contain an embryo of a new plant.
- Consist of seed coat, endosperm (food source), and embryo (radicle and cotyledon).
