What are the two parts of the stamens in a flower?
Anther and Filament
How many stamens are typically found in a flower?
The number of stamens can vary, but in general, a flower has multiple stamens.
What is the function of a stem?
The stem conducts water from roots to the leaves and food from leaves to other parts of the plant.
Which type of roots do plants with leaves having reticulate venation usually have?
Plants with leaves having reticulate venation usually have tap roots.
What are the parts of a flower?
The parts of a flower are sepals, petals, stamens, and pistil.
Which part of the plant anchors it firmly in the soil?
Roots anchor the plant firmly in the soil.
What do green leaves use to make their food through photosynthesis?
Green leaves use carbon dioxide and water in the presence of sunlight to make their food.
Which process involves leaves giving out water vapor?
Transpiration involves leaves giving out water vapor.
Study Notes
Plant Structure
- A flower has four parts: sepals, petals, stamens, and pistil
- Stamens consist of anthers and filaments
- Pistil consists of stigma, style, and ovary
- Ovary is the lowermost and swollen part of the pistil
- Ovary contains ovules, which are small bead-like structures
Leaf Structure
- Leaves have reticulate or parallel venation
- Leaves lose water through transpiration
- Transpiration is the process of water evaporation from leaves
- Leaves also make food by photosynthesis using carbon dioxide and water in the presence of sunlight
Root Structure
- Roots absorb water and minerals from the soil
- Roots also anchor the plant firmly in the soil
- There are two types of roots: tap root and fibrous root
- Plants with reticulate venation have tap roots, while plants with parallel venation have fibrous roots
Stem Function
- Stem conducts water from roots to leaves and other parts of the plant
- Stem also conducts food from leaves to other parts of the plant
Flower Function
- Flowers have different parts, including sepals, petals, stamens, and pistil
- Sepals and petals can be separate or joined together
- Stamens consist of anthers and filaments, and pistil consists of stigma, style, and ovary
Watering Plants
- Plants need water to survive
- Roots absorb water from the soil
- Transpiration helps to release excess water from leaves
- Watering plants regularly is essential for their growth and survival
Test your knowledge on leaf venation patterns such as reticulate and parallel, and learn about the functions of leaves. Explore the names of plants with different venation types and understand the significance of midrib veins.
