Which part of the plant cell is responsible for storing water and maintaining turgor pressure?
Show answer
Answer: C. Vacuole
The vacuole in a plant cell is a large, membrane-bound sac that stores water, nutrients, and waste products. It also plays a crucial role in maintaining turgor pressure, which gives the plant its rigidity.
Which part of the plant cell is responsible for protein synthesis?
Show answer
Answer: B. Ribosome
Ribosomes are small organelles responsible for synthesizing proteins by translating messenger RNA (mRNA) into polypeptide chains.
Which of the following is a function of the stem?
Show answer
Answer: C. Support for leaves and flowers, and transport of water and nutrients
The stem provides structural support to the plant, holds leaves and flowers, and contains vascular tissues (xylem and phloem) for transporting water, minerals, and food.
The process by which gametes (sperm and egg) fuse to form a zygote is called:
Show answer
Answer: B. Fertilization
Fertilization is the fusion of male and female gametes, a key event in sexual reproduction.
What gas do plants absorb from the atmosphere for photosynthesis?
Show answer
Answer: C. Carbon Dioxide
Plants take in carbon dioxide from the atmosphere through their stomata to use as a reactant in photosynthesis.
