Plant Cells Compared with Animal Cells

Animal cells do not have a cell wall. Instead of a cell wall, the plasma membrane (usually called cell membrane when discussing animal cells) is the outer boundary of animal cells. Animal tissues therefore require either external or internal support from some kind of skeleton.  Frameworks of rigid cellulose fibrils thicken and strengthen the cell walls of higher plants.  Plasmodesmata that connect the protoplasts of higher plant cells do not have a counterpart in the animal cell model.  During telophase of mitosis, a cell plate is formed as the plant cell begins its division.  In animal cells, the cell pinches in the center to form two cells; no cell plate is laid down.  Centrioles are generally not found in higher plant cells, while they are found in animal cells. Animal cells do not have plastids, which are common in plant cells (chloroplasts). Both cell types have vacuoles, however, in animal cells vacuoles are very tiny or absent, while in plant cells vacuoles are generally quite large.

	Animal Cell	Plant Cell
Nucleus:	Present	Present
Cilia:	Present	It is very Rare
Shape:	Round	Rectangular
Centrioles:	Present in all animal cells	Only present in lower plant forms.
Vacuole:	One or more small vacuoles (much smaller than plant cells).	One, large central vacuole taking up 90% of cell volume.
Plastids:	No	Yes
Ribosomes:	Present	Present
Endoplasmic Reticulum (Smooth and Rough):	Present	Present
Flagella:	May be found in some cells	May be found in some cells
Lysosomes:	Lysosomes occur in cytoplasm.	Lysosomes usually not evident.
Microtubules/ Microfilaments:	Present	Present
Plasma Membrane:	Yes; only cell membrane	Yes; cell wall and a cell membrane
Cell wall:	None	Yes
Mitochondria:	Present	Present
Cytoplasm:	Present	Present
Chloroplast:	Animal cells don't have chloroplasts	Plant cells have chloroplasts because they make their own food

Examine the photo on the right: This photo shows a human cheek cell which has been magnified about 400 times The nucleus is clearly visible. It has been stained with Methylene Blue dye You can also see the cell membrane

Examine the diagram on the right: The Cytoplasm is the jelly like material which makes up the cell The Nucleus controls the activities of the cell and is responsible for reproduction. The cell may contain small Vacuoles which contain food. The Cell Membrane protects the cell and allows food to pass into the cell

Examine the Photo on the right: The photograph shows plant cells at low power. These cells have been stained to in order to show greater detail Each cell has a central nucleus. Clearly visible is a cell wall surounding each cell
Examine the Photo on the right: The photograph shows plant cells when viewed at high power You should notice that the cells are three-dimensional The nucleus and the cell wall are clearly visible
Examine the diagram on the right: This diagram represents a typical plant cell. The nucleus is responsible for reproduction. The vacuoles store food The cytoplasm is the jelly like material which makes up the cell Most plant cells above the ground also have chloroplasts. These are responsible for making food through the process of photosynthesis

Plant and Animal Cells generally contain. A Nucleus which controls contains chromosones A Cell Membrane which allows materials to pass into and out of the cell A Cytoplasm A Vacuole or Vacuoles The main differences between plant and animal cells are. Animal cells have no cell walls. Animal cells have no chloroplasts. Plant cells have larger permanent vacuoles

The nucleus. The nucleus helps regulate the cell's entire activities such as how much of a hormone to produce or what to let through the cell membrane. It contains the nucleolis as well, which is an organelle which helps produce ribosomes, which are the filaments that make rough endoplasmic reticulum rough and excrete waste

Nucleus is the control center of the cell as it contains the chromosomes which are the hereditary carriers of any organism to the next generation.

Its significance includes
* Controls all metabolic activities of cell
* Passes on genetic information to next generation during reproduction
* Participates in cell division

Tissue is a cellular organizational level intermediate between cells and a complete organism. Hence, a tissue is an ensemble of cells, not necessarily identical, but from the same origin, that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues.

. State the similarities and differences between animal cells and plant cells. 2. Why the nucleus is called the control centre of the cell? 3. What is tissue? What word means collection of tissues doing one particular job? 4. Name the type of cells which lines the inner cheek 5.when cells were discovered and by whom.

Answer : first: onions are underground, and are root-like, and do not need to perform photosynthesis to produce organic compounds for food for the rest of the plant. The onion bulb stores the organic product made by the onion plant's leaves which are above surface. 1. animal cells and plant cells have many of the same organelles, some including cell membrane, nucleus (generally), cytoplasm, and they're both eukaryotic cells. some differences include that no animal cells have chloroplasts and animal cells don't do photosynthesis....there are a lot of similarities and differences...found in a bio textbook. 2. nucleus has DNA and controls the functions of the cell, ie response to external stimuli and cell replication 3. tissue means collection of cells performing the same operation, eg. tissue in stomach secretes digestive enzymes, or tissue in epidermis acts to protect internal organs and contents of body from infection etc. 4. epithelial 5.
