assess the capibilities of plant and animal cell owing to presence or absence of choloroplast and cell wall
Answers
Answer:
Centrosomes and lysosomes are found in animal cells, but do not exist within plant cells.
The lysosomes are the animal cell’s “garbage disposal”, while in plant cells the same function takes place in vacuoles.
Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, which are not found within animal cells.
The cell wall is a rigid covering that protects the cell, provides structural support, and gives shape to the cell.
The chloroplasts, found in plant cells, contain a green pigment called chlorophyll, which captures the light energy that drives the reactions of plant photosynthesis.
The central vacuole plays a key role in regulating a plant cell’s concentration of water in changing environmental conditions.
Key Terms
protist: Any of the eukaryotic unicellular organisms including protozoans, slime molds and some algae; historically grouped into the kingdom Protoctista.
autotroph: Any organism that can synthesize its food from inorganic substances, using heat or light as a source of energy
heterotroph: an organism that requires an external supply of energy in the form of food, as it cannot synthesize its own
Animal Cells versus Plant Cells
Each eukaryotic cell has a plasma membrane, cytoplasm, a nucleus, ribosomes, mitochondria, peroxisomes, and in some, vacuoles; however, there are some striking differences between animal and plant cells. While both animal and plant cells have microtubule organizing centers (MTOCs), animal cells also have centrioles associated with the MTOC: a complex called the centrosome. Animal cells each have a centrosome and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, whereas animal cells do not.
