Question

question 1
a large organelle found in a eukaryotic cell that genetically controls the cells activities is the
a. vacuole.
b. flagellum.
c. centriole.
d. nucleus.
e. chloroplast.

question 2
chloroplasts are the structures in which
a. new organelles are made.
b. sunlight energy is converted into chemical energy.
c. genetic information is used to make proteins.
d. cell division is controlled.
e. chemical energy is stored in the form of atp.

question 3
chromatin is a series of entangled threads composed of
a. cytoskeleton.
b. dna and protein.
c. fibrous proteins.
d. membranes.
e. microtubules.

question 4
an organelle consisting of a series of flattened sacks called cisternae is the
a. mitochondrion.
b. rough endoplasmic reticulum.
c. peroxisome.
d. flagellum.
e. golgi apparatus.

Explanation:

• Question 1: The nucleus contains the cell's genetic material (DNA) and controls cellular activities. Vacuoles store substances, flagella are for movement, centrioles are involved in cell - division, and chloroplasts are for photosynthesis.
• Question 2: Chloroplasts are the site of photosynthesis where sunlight energy is converted into chemical energy in the form of glucose. They are not involved in making new organelles, protein - synthesis from genetic information, cell - division control, or ATP storage in the way described.
• Question 3: Chromatin is composed of DNA and histone proteins. It is not made of cytoskeleton, fibrous proteins alone, membranes, or microtubules.
• Question 4: The Golgi apparatus consists of a series of flattened sacs called cisternae. Mitochondria are the power - houses of the cell, rough endoplasmic reticulum is studded with ribosomes, peroxisomes contain enzymes for breaking down substances, and flagella are for movement.

Answer:

Question 1: D. nucleus
Question 2: B. sunlight energy is converted into chemical energy
Question 3: B. DNA and protein
Question 4: E. Golgi apparatus
