Roots
What is the main function of plant roots?
(Answer: To absorb water and nutrients from the soil.)
What is the main function of plant leaves?
To make food for the plant through photosynthesis.
What part of the plant is responsible for capturing sunlight?
Leaves
What is the main purpose of a fruit?
To protect the seeds and help with their dispersal.)
What are the basic things that all plants need to survive?
Water, sunlight, air (carbon dioxide), and nutrients.)
Why do some plants have very deep roots?
(Answer: To reach water deep underground or for stability.
Why are most leaves green?
Because they contain chlorophyll, which helps absorb sunlight.)
What is the flat part of a leaf called, and what is its function?
The blade, which helps capture sunlight.)
How do animals help in the dispersal of fruits and seeds?
They eat the fruit and spread the seeds through droppings or by carrying them.)
Why do plants need sunlight?
To perform photosynthesis, which helps them produce food.)
How do plant roots help prevent soil erosion?
They hold the soil together with their network
What happens during photosynthesis in leaves?
The plant uses sunlight, carbon dioxide, and water to produce oxygen and glucose.)
Why do some leaves change color in the fall?
Chlorophyll breaks down, revealing other pigments like carotenoids and anthocyanins
What is the difference between fleshy and dry fruits?
Fleshy fruits are soft and moist, like apples, while dry fruits are hard, like nuts or grains.)
How do plants absorb water and nutrients from the soil?
Through their roots.)
What is the role of root hairs in a plant?
Root hairs increase the surface area for absorbing water and nutrients
How do stomata in leaves help the plant?
They allow gases (carbon dioxide and oxygen) to move in and out and help control water loss.)
What is transpiration, and how does it occur in leaves?
It is the process of water vapor leaving the plant through the stomata.)
How does the fruit form from a flower?
The ovary of the flower develops into the fruit after fertilization.)
What happens to a plant if it doesn’t get enough carbon dioxide?
It cannot perform photosynthesis effectively and may not grow properly.)
Explain how roots can form symbiotic relationships with fungi (mycorrhizae) and how this benefits both the plant and the fungi.
The fungi help the plant absorb nutrients, and the plant provides the fungi with sugars.
Explain how leaves adapt in desert plants to conserve water.
Desert plants may have small or thick leaves, waxy coatings, or spines to reduce water loss.)
Explain how different types of leaves are adapted to their environments (e.g., broad leaves in rainforests vs. needle-like leaves in conifers).
Broad leaves increase surface area for photosynthesis in low light, while needle-like leaves reduce water loss in dry or cold environments.)
Explain how seed dispersal methods (wind, water, animals) help plants spread to new areas.
These methods reduce competition and help plants grow in different places.)
How does the amount of light, water, and nutrients affect the growth of different types of plants?
Some plants need full sunlight, while others prefer shade; too much or too little water/nutrients can stunt growth or even kill the plant.)
