Question

which organelle is critical for cell division in animal cells? 3 points centrioles cilia vacuoles which statement best describes the job of the mitochondria in a cell? 3 points a. they store water for the cell b. they control what enters and leaves the cell c. they produce energy for the cell d. they help make proteins what is the main job of the golgi apparatus in a cell? * 3 points a. to break down old cell parts b. to package and ship proteins c. to store dna d. to control the cells activities

Explanation:

• First question: Centrioles are crucial for forming the spindle fibers during cell division in animal cells. Cilia are for movement (like in some cells to move substances). Vacuoles are for storage (e.g., water, nutrients in plant cells more prominently in some cases).
• Second question: Mitochondria are the power - houses of the cell. They produce energy (ATP) through cellular respiration. Option A is for vacuoles (in some cells), B is for cell membrane, D is for ribosomes (in part, along with rough ER).
• Third question: The Golgi apparatus modifies, packages, and ships proteins (and lipids). Option A is for lysosomes, C is for the nucleus (stores DNA), D is for the nucleus (controls cell activities).

Answer:

• First question: centrioles
• Second question: C. They produce energy for the cell
• Third question: B. To package and ship proteins
