Flashcards

Mitochondrion function

The mitochondrion is the site of cellular respiration, producing energy for the cell.

Plant cell wall

A rigid structure surrounding plant cells, providing support and shape.

Chloroplast function

Chloroplasts are the sites of photosynthesis in plant cells, converting light energy into chemical energy.

Nucleus membrane - Animal cells

Animal cells have a membrane surrounding their nucleus, but Bacterial cells do not.

Study Notes

Cell Structure Overview

Mitochondrion, known as the "powerhouse" of the cell, is responsible for energy production through cellular respiration.
Chloroplasts are the sites of photosynthesis in plant cells, converting sunlight into energy.

Differences in Cell Types

Plant cells feature a rigid cell wall, while animal cells have flexible membranes without a cell wall.
Animal cells possess a membrane-bound nucleus, whereas bacterial cells lack this membrane, making them prokaryotic.
