Question

which does not correctly match the organelle with its function?
cytoskeleton maintains shape
cell membrane regulates transport
ribosomes make proteins
lysosomes transport materials
question 14
what gel - like substance fills the cell and is the site of reactions?
cytoplasm
nucleus
chloroplast
endoplasmic reticulum

Explanation:

• First question:
• The cytoskeleton indeed maintains the cell's shape.
• The cell membrane regulates the transport of substances in and out of the cell.
• Ribosomes are the sites of protein synthesis.
• Lysosomes are responsible for breaking down waste materials and cellular debris, not transporting materials. Vesicles are more involved in transport.
• Second question:
• Cytoplasm is the gel - like substance that fills the cell and is the site of many cellular reactions.
• The nucleus contains the cell's genetic material.
• Chloroplasts are involved in photosynthesis in plant cells.
• The endoplasmic reticulum is involved in protein and lipid synthesis and transport.

Answer:

• First question: Lysosomes transport materials.
• Second question: Cytoplasm.
