Tap to reveal answer
One of the primary differences between plant cells and animal cells is that plant cells must be able to undergo photosynthesis. Photosynthesis takes place in the chloroplasts, which contain the pigment chlorophyll. Chloroplasts are not found in animal cells, but are found in plant cells.
Both animal and plant cells contain Golgi bodies, smooth endoplasmic reticulum, and mitochondria.

Mitochondria are the only organelle defined correctly. The main processes of cell respiration, namely the electron transport chain, occur in the mitochondria to produce energy in the form of ATP. Because of this, mitochondria are known as the "powerhouses" of the cell.
Ribosomes are responsible for transcribing RNA and creating new proteins. The Golgi body packages proteins into vesicles that can be transported out of the cell. Lysosomes contain enzymes that can digest old or damaged proteins. The smooth endoplasmic reticulum is responsible for synthesizing lipids and for degrading toxins, such as alcohol.

Nonmembranous organelles are always in contact with cytosol.
Membranous organelles are surrounded by membranes that isolate their contents from the cytosol.
Ribosomes are freely scattered in the cytoplasm and thus are nonmembranous organelles.

Tap to reveal answer
Mitochondria are organelles that have an unusual double membrane. An out membrane surround the entire organelle, and a second, inner membrane contains numerous folds, called cristae. Cristae increase the surface area exposes to the matrix of mitochondria.

Tap to reveal answer
The plasmalemma (plasma membrane) has a complex structure composed of phospholipids, proteins, glycolipids, and cholesterol. The phospholipids form two distinct layers that don't allow dissolved ions and water-soluble compounds to cross the plasmalemma. This makes the plasmalemma effective in isolating the cytoplasm from the surrounding fluid environment.

Which is not a major function of the endoplasmic reticulum (ER)?
Which is not a major function of the endoplasmic reticulum (ER)?
Tap to reveal answer
The ER has four major functions: Synthesis, storage, transport, and detoxification.
Synthesis - ER membrane contains enzymes that manufacture carbohydrates, steroids, and lipids.
Storage - ER holds synthesized molecules absorbed from the cytosol.
Transport - Substances travel from place to place within the cell inside the ER.
Detoxification - Cellular toxins are absorbed by ER and neutralized by enzymes in ER membrane.

Plant cells have chloroplasts, which is the organelle where photosynthesis takes place, but animal cells do not. Plant cells contain both a cell membrane and a cell wall, but animal cells only have a cell membrane. Plant cells have a large vacuole and animal cells have small vacuoles. Animal cells have centrioles, but plant cells do not. All other organelles are found in both plant and animal cells.
