In Science class, Jackson was looking at plant and animal cells through a microscope. The image below is of the cell he had seen last. Jackson was unsure of what it was. Determine what type of cell the image represents and explain why.
Plant cell — it has a rigid cell wall that gives it a rectangular shape and includes structures not found in animal cells.
Animal cell — the cell has a round/irregular shape, no cell wall, and it lacks chloroplasts.
Plant cell — chloroplasts are visible throughout the cell.
Animal cell — the cell contains chloroplasts that help make food.
A large protein molecule that uses energy is trying to exit the cell.
What form of transport would it use?
Passive transport, moves without energy.
Active transport requires energy to move.
Passive transport allows molecules to move freely
Active transport because it doesn't use energy
A large protein molecule that uses energy is trying to exit the cell.
Would this form of transport be endocytosis or exocytosis?
Endocytosis — because the large molecule is entering the cell.
Endocytosis — because the molecule is using energy to move.
Exocytosis — because the large molecule is leaving the cell and needs energy to exit.
Exocytosis — because the cell is trying to bring the molecule inside.
A plant cell suddenly becomes unable to make enough energy to support growth. Analysis of the cell shows that both the chloroplasts and mitochondria are functioning normally. Which organelle failure would MOST likely explain why energy production is still disrupted?
