What are the four main things plants need to survive?
Sunlight, water, carbon dioxide, and nutrients
What sugar is produced during photosynthesis?
Glucose or C6H12O6
Why is nitrogen important for plant growth?
It helps plants grow green leaves and supports chlorophyll production
How does potassium help keep plants healthy?
It helps overall health and disease resistance
What might happen to a plant if its roots are damaged?
The plant may not absorb enough water/nutrients and could die
Which part of the plant absorbs water and nutrients?
Roots
Which part of the PLANT is responsible for making food?
How does water help plants grow?
It transports nutrients and helps maintain structure
How does carbon dioxide enter the plant?
Through the stomata
How would overwatering affect a plant’s ability to get oxygen?
Roots may not get enough oxygen, leading to root rot
What is the name of the process plants use to make their own food?
What do xylem and phloem transport?
Xylem transports water
Phloem transports glucose and other nutrients
Explain how roots and stems work together to support the plant.
Roots absorb water/nutrients
Stems transport water and nutrients throughout the plant
Why are decomposers important for plant growth?
They break down dead matter and return nutrients to the soil
A farmer wants bigger fruit from crops. Which nutrient should they focus on and why?
Phosphorus, because it helps with fruit and seed development
What are the THREE main macronutrients plants need from the soil?
Nitrogen, phosphorus, potassium
What is the main function of flowers?
Reproduction
Why are leaves called the “food factories” of the plant?
They perform photosynthesis to make food
A plant has yellow leaves and is not growing well. Which nutrient might it be lacking and why?
Nitrogen, because it helps leaves stay green and grow
How are photosynthesis and cellular respiration opposite processes?
Photosynthesis stores energy
Cellular respiration releases energy
What gas do plants take in during photosynthesis?
Carbon dioxide or CO2
What process releases energy from glucose in plants?
cellular respiration
What role does phosphorus play in plant development?
It supports root growth and flower/fruit development
If a plant is not getting enough sunlight, how will this affect photosynthesis?
Photosynthesis would decrease, so the plant makes less food
What would happen if a plant could perform photosynthesis but not cellular respiration?
The plant would not be able to release energy for growth and survival
