Study Notes
Types of Roots
- A taproot is a single, large central root with smaller side roots that branch out from it.
- A fibrous root forms a clump of short, threadlike divisions.
Flower
- The reproductive organ of a flowering plant is a flower.
- Flowers are a food source for other living organisms.
Seed
- A seed is a reproductive structure comprised of a plant embryo and its stored food.
Fruit
- Fruits house and protect seeds.
- Fruits may also aid in dispersing seeds to new locations.
Leaf
- Leaves are organs responsible for photosynthesis, a process where sunlight, water, and carbon dioxide are used to create sugars.
Parts of the Leaf
- The blade (lamina) is the flat, broad section of the leaf and contains cells that perform photosynthesis.
- Veins are tube-like structures that transport water, minerals, and sugars throughout the blade.
- Monocot leaf veins are usually parallel.
- Dicot leaf veins are usually branched.
- The petiole is the short stalk that connects the leaf to the stem, providing support and enabling the transport of fluids between the leaf and the stem.
Parts of the Leaf
- The midrib is the central vein of the leaf that travels the length of the leaf and branches to each side to produce veins of vascular tissue.
- The margin is the edge of the leaf.
- Lamina (leaf blade) is the flat, broad part of the leaf.
- The petiole is the stalk that attaches the leaf to the stem.
- Veins are the vascular tissue that transports water and nutrients.
- The tip is the pointed end of the leaf.
Leaf Classification
- A simple leaf has an undivided blade.
- A compound leaf has a divided blade, forming leaflets.
- A palmately compound leaf has leaflets that radiate outwards from the end of the petiole.
- Pinnately compound leaf has leaflets arranged along the middle vein.
Stem
- Stems are the support systems of plants.
- Stems are delivery agents for nutrients and water stored in the roots.
- Stems transfer nutrients to other plant parts in the form of glucose.
- Stems also transfer food from the leaves to other parts of the plant.
Roots
- Roots are responsible for transferring necessary nutrients to the plant.
- Roots are responsible for delivering water and minerals to the plant.
