1. which organelles are working together to build and distribute (share) macromolecules like proteins, carbs, or lipids to other organelles?

a. mitochondria, chloroplasts, cytoplasm
b. ribosome, endoplasmic reticulum, golgi body
c cell membrane, lysosome, nucleolus
d. vesicle, flagella, cilia

Explanation:

Question 23:

Lysosomes break down waste materials and cellular debris, contributing to the formation of urine - like waste in kidneys. Vacuoles mainly store substances, golgi apparatus modifies and packages proteins, and chloroplasts are for photosynthesis.

Question 24:

Ribosomes are the sites of protein synthesis where they read mRNA (a type of RNA) to make proteins including enzymes during translation. Endoplasmic reticulum helps in protein and lipid synthesis but not the direct reading of RNA for enzyme - making in translation. Nucleolus makes ribosomal RNA, and golgi apparatus modifies and packages proteins.

Question 25:

Centrosomes contain centrioles which organize spindle fibers during mitosis in eukaryotic cells. Pili are related to bacterial conjugation, and nucleases are enzymes that cut nucleic acids.

Question 26:

Mitochondria are involved in cellular respiration to produce energy, chloroplasts are involved in photosynthesis, and cytoplasm is the site where many metabolic reactions occur. Other options do not involve organelles mainly related to energy - gaining in these processes.

Question 27:

Ribosomes synthesize proteins, endoplasmic reticulum helps in the synthesis and folding of proteins and lipids, and golgi apparatus modifies, packages, and distributes these macromolecules to other organelles. Other options do not have the correct combination for building and distributing macromolecules.

Answer:

1. b. The lysosome
2. d. Ribosomes
3. c. Spindle fibers and Centrioles
4. a. Mitochondria, chloroplasts, cytoplasm
5. b. Ribosome, endoplasmic reticulum, golgi body
