These can include proteins, energy compounds, and nutrients. It is located near the nucleus and surrounded by ribosomes.
Why are cell walls porous?
Besides providing the structure, strength, and rigidity of the cell, the cell walls are also porous and allow the movement of materials into and out of the cell. These channels are regulated to ensure that harmful compounds are kept out.
Why are plant cells so rigid?
Plant cells are very rigid because of their cell wall, a component that does not exist within animal cells. The plant cell wall was inherited from our prokaryotic ancestor and became a highly specialized part of the cell. The rigidity comes from a complex series of cross-linked structures made of cellulose and lignin that reinforce the wall.

What is the outermost part of a plant cell?
The outermost portion of a plant cell is the cell wall. This is also a part that animal cells do not have. The function of a cell wall is to give the cell rigidity and support, as well as allow for the circulation of water and minerals. When a vegetable is bitten into, it gives off a nice crunchy sound. This is due to the cell wall. The cell wall is made up of complex polysaccharides (poly-many, saccharide-sugar) like pectin and glycan, along with some microfibers. The cell wall also helps fight off disease by being another barrier between the outside and the inside of the cell.
How does the Golgi apparatus work?
The Golgi works closely with rough ER to get the synthesized compounds to the right places. Those vesicles can either go somewhere else in the cell, to the cell membrane for repair or transported out of the cell altogether.
What is the cell membrane?
Every cell has a cell membrane, whether it be a plant or animal. A cell membrane is a division between the outside environment and the inside protoplasm of the cell. The cell membrane is made up of phospholipids and proteins; it is said to be a lipoprotein layer. The cell membrane is also called the cytomembrane or plasma membrane. It allows for the passage of certain compounds through channels that are highly regulated, therefore it is a semipermeable layer.

What is the outermost layer of a plant cell called?
As previously mentioned, a plant cell is a self-contained unit. It's surrounded by not one but two enclosures. The outermost layer is called the cell wall and is unique to plant cells. Like an actual wall, this layer is fairly rigid.
What is the second covering of the cell?
Inside the cell wall is the second covering, the cell membrane. Thin and flexible, it keeps the contents of the cell intact much like a balloon holding water. This sac-like covering is semi-permeable, meaning select particles can move through the membrane.
What are the ribosomes?
Ribosomes are the producers of our factory-like cell. They are responsible for making proteins, which are a crucial part of every living thing. The genetic instructions laid out by the DNA are brought to the ribosomes by the traveling messenger of our factory, which is a molecule known as mRNA.
What are the structures of a plant cell that hold pigments?
Chloroplasts are easy to find and observe. They are "chlorophyll-bearing plastids." Plastids are cellular structures of a plant cell that generally hold pigments. Plants have other kinds of plastids besides chloroplasts. For instance, one type of plastid called chromoplastid contains two kinds of dyes: carotene, which gives cream, white, yellow, orange, and red colors and xanthophylls, which provide bright yellow and brown colors. Not all plant pigments are inside plastids. For instance, anthocyanin, a purple dye, is dissolved in the cytoplasm.

Golgi bodies are responsible for the creation of lysosomes in a plant cell. 6e. Endoplasmic Reticulum. The endoplasmic reticulum is the intricate system of small tubes or cavities, the endoplasmic reticulum, which connects the cell membrane and the nuclear membrane at several points.
Why are plastids important?
Plastids have many essential metabolic pathways that are important for plant growth and development.
How does the cell wall differ from the cell membrane?
First, it contains a combination of fat, protein, and carbohydrate molecules. Second, it is relatively rigid, while the cell membrane is elastic. Its rigidity permits the plant cells to maintain their shape.

The following points highlight the nine components of a typical plant cell.
Why do plants have more than one nucleus?
Even in some higher plants more than one nucleus may arise due to disease and other reasons. Formation of many nuclei in a cell may be due to (i) repeated division of the nucleus without corresponding cytoplasmic division; and (ii) absorption of walls between the cells.

Protoplasm exhibits streaming movements of different types which are commonly noticed in amoebas, slime moulds, and particularly in the plant cells with large vacuoles.
Where are plastids found in plants?
Plastids are distinct living bodies or organs embedded in the cytoplasm of the plant cells. They are much smaller than the nuclei and usually a good number of them occur in a cell. Plastids are of universal occurrence in the plant cells with the exception of lower plants like bacteria, fungi, slime moulds and blue-green algae. Like nucleus plastids do not arise de novo, but originate from pre-existing ones.
What is the function of lysosomes?
Due to pressure of hydrolytic enzymes lysosomes take active role in breakdown of different cell substances. The materials in the lysosome often form crystals. The function of lysosome membrane is that of separating the hydrolytic enzymes from other parts of the cell, thus avoiding self-digestion.
What is the most important component of a chromosome?
The most important constituent of the chromosome seems to be the nucleic acid —DNA, deoxyribose nucleic acid, which is the actual chromatic material causing staining of the chromosomes. Differential staining at different regions of chromosome means difference in its chemical nature. The nucleus contains the basic genetic information of the cell in form of long strands of this chemical material DNA, the molecules of which are believed to be in the form of double strands of intertwined helices in the chromosomes.
