Study Notes
Plant Systems
- Plants, diverse in shape and size, share fundamental parts integrated into systems.
- The shoot system comprises aerial parts; the root system is underground.
- Plants are made up of different parts, each with its own function, working together to allow the plant to thrive.
Leaf Structure and Function
- Leaves vary in appearance (thorns, small leaves, colored leaves, etc.), but share similar functions.
- Key leaf parts include petiole (leaf stalk), blade (flat surface), veins, and midrib (central vein).
- Leaf margins influence leaf shape and aid in plant identification.
- Leaves are the plant's "food factory" or "kitchen."
- Chlorophyll, a green pigment, captures sunlight's energy for photosynthesis, converting water and carbon dioxide into food.
- Oxygen is released as a byproduct, essential for human and animal respiration.
- Leaves can be colored other than green (red, orange, yellow, purple) due to different pigments and varying chlorophyll content; photosynthesis still occurs.
- Some leaves, like cactus thorns, are modified.
- Tiny basil leaves have fragrance.
- Leaf stalks are called petioles; leaf flat surfaces are called blades; thin lines across the blade are called veins; the central vein is the midrib.
- Leaf margins affect shape and help identify plant species.
- The stalk connects the leaf to the stem. Some leaves lack a leaf stalk.
Root System
- Roots, varying in shape, size, and color, anchor the plant and absorb water and mineral salts for growth.
- Roots firmly hold the plant in the soil.
- Two root system types: taproot (e.g., mustard, mango, radish) and fibrous roots (e.g., wheat, rice, grasses).
- Roots like carrot, turnip, and beetroot store excess food and are edible.
- Roots depend on the energy produced by photosynthesis in the leaves.
- Without roots water and mineral salts cannot be absorbed to support the leaves and the plant.
Stem Function
- The stem connects roots and leaves, enabling upward water/mineral movement and downward food movement.
- It supports leaves for optimal sunlight exposure (photosynthesis).
- Stem types: strong (e.g., soft, woody, hard) providing structure, weak stems (e.g., creepers, climbers) needing external support.
- Some stems store excess plant food.
- Examples include: soft stems (mint, coriander), thin woody stems (rose, jasmine), hard woody stems (mango, banyan), and weak stems (pumpkin, watermelon, bitter gourd, money plant).
Flower and Fruit
- Flowers develop into fruits, containing seeds for reproduction.
- Fruits: some contain many seeds (e.g., pomegranate, kiwi); others have one (e.g., plum, peach, mango).
- Edible seeds: peas, pomegranate, guava, cashew. Inexible seeds: papaya, litchi, apple.
- Seeds germinate into new plants under suitable conditions.
Variations in Pigments
- Leaves can display colors other than green (red, orange, yellow, purple) due to other pigments and reduced chlorophyll.
- Photosynthesis still occurs.
Photosynthesis
- Leaves produce food; plants store it.
- Most leaves are green due to chlorophyll, capturing sunlight for photosynthesis.
- Leaves use water and carbon dioxide (from air) in sunlight to prepare food.
- Photosynthesis releases oxygen, used by humans and animals for breathing.
Other Information
- A plant's different parts work together as a system.
- Parts above ground are part of the shoot system. Parts below ground belong to the root system.
- Plant parts have diverse appearances but similar functions.
- Roots hold plants in the ground and absorb water and mineral salts.
- Water and minerals move up stems. Food moves down stems from leaves.
- Stems support leaves for sunlight.
- Different stem types include soft, woody, and hard, strong or weak.
- Flowers produce seeds in fruits; seeds grow into new plants.
- Fruits contain varying numbers of seeds (some many, some one).
- Some fruits have edible seeds (peas, pomegranate, guava, cashew). Others do not (papaya, litchi, apple).
- The process of a seed growing into a new plant is called germination.
- Germination requires the correct amounts of air, water, sunlight, temperature, and nutrients.
