Study Notes
Plants Around Us
- Plants are grouped by stem type: trees, shrubs, herbs, creepers, and climbers
- Trees are tall with thick trunks and many branches. They live for many years. Examples include Banyan, mango, and coconut
- Climbers have weak stems and need support to stand. Examples include grapevine, money plant, and pea
- Shrubs have hard, woody stems with small branches and live for several years. Examples include hibiscus, rose, and jasmine
- Creepers have very weak stems and grow along the ground. Examples include pumpkin and watermelon
- Herbs are small plants with soft, short stems and live for a few months. Examples include grass, coriander, mint, rice, wheat, and spinach
Parts of a Plant: Root System
- The root system is the part of the plant below the ground
- Two types of root systems: taproot and fibrous
- Taproot system has one main root with smaller branches. Examples include neem, mango, pea, carrot, radish, turnip, and mustard
- Fibrous root system has a cluster of thin roots. Examples include maize, wheat, sugarcane, rice, and grass
- Roots hold the plant in place, absorb water and nutrients, and prevent soil erosion
Parts of a Plant: Modifications of Roots
- Roots can be modified for different functions, including food storage
- Roots may become fleshy to store food(e.g., carrot, beetroot, radish, turnip, sweet potato)
- Prop roots support the plant, like in banyan trees
- Stilt roots support the plant base, like in maize, sugarcane, coconut
- Breathing roots (pneumatophores) help plants in wet, salty areas get oxygen. Examples: mangrove plants
- Climbing roots help plants climb, like in betel, black pepper, and money plant
- Parasitic roots get nutrients from other plants like dodder
Parts of a Plant: Stem
- The stem connects the roots to the rest of the plant, supporting it and transporting nutrients
- Stems have nodes (where leaves, branches, or buds grow) and internodes (the space between nodes).
- The apical bud is at the tip of the stem and responsible for growth, while axillary buds (at the nodes) grow into leaves, stems, or additional buds
Parts of a Plant: Modifications of Stems
- Stems can be modified for food storage like in ginger, potato, onion
- Stems can be modified into tendrils to support climbing plants (e.g., grapevine, cucumber)
Parts of a Plant: Leaves
- Leaves come in different shapes and colours and are responsible for food production (photosynthesis)
- Leaves have veins for support and transport of water, minerals and food
- Two main types of leaf venation: reticulate (net-like) and parallel (parallel lines)
- Leaves can be modified for water storage, food manufacture (cactus-like), and protection (thorns)
Parts of a Plant: Functions of Leaves
- Leaves produce food through photosynthesis
- Leaves absorb gases (carbon dioxide, oxygen) through stomata
- Leaves lose water through transpiration
Parts of a Plant: Flowers
- Flowers are the colourful and fragrant reproductive parts of plants
- A flower has male parts (stamens) – filament and anther, and female parts (pistil) – stigma, style, and ovary
- Petal- bright colored part of the flower that attracts insects for pollination with scents and colors
- Sepals and pedicel
- Thalamus
- Structure of a flower
Parts of a Plant: Pollination
- Pollination is the transfer of pollen from the anther to the stigma of a flower
- Flowers are helped by pollinating agents like insects, birds, wind, and water
- Two types of pollination: self-pollination (pollen to the same or other flower on the same plant) and cross-pollination (pollen to a different plant)
