The cell wall (found only in plant cells) protects the plant cell, maintains its shape, and prevents excessive uptake of water. A young plant first secretes a relatively thin and flexible wall called the primary cell wall. Between primary walls of adjacent cells is the middle lamella, a thin layer rich in sticky polysaccharides called pectins. The middle lamella glues the cells together. When the cell matures and stops growing, it strengthens its wall. Some plant cells do this simply by secreting hardening substances into the primary wall. Other cells add a secondary cell wall between the plasma membrane and the primary wall. The secondary wall, often deposited in several laminated layers, has a strong and durable matrix that affords the cell protection and support. Wood, for example, consists of mainly secondary wall.
What else can I help you with?
The structure and properties of the cell wall allow it to be selective and maintain homeostasis True or false?
True. The cell wall is selectively permeable, allowing only certain molecules to pass through, which helps maintain homeostasis by regulating what enters and exits the cell. Additionally, the cell wall provides structural support and protection for the cell.
Is it true that animal cells have cell walls?
No, animal cells do not have cell walls. Instead, they are surrounded by a flexible membrane called the plasma membrane. Cell walls are found in plant cells, fungi, algae, and some bacteria, where they provide structural support and protection.
Is it true that cell wall lies inside the cell membrane?
The cell membrane is the outer boundary in all cells that do not have a cell wall (such as animal cells). The cell wall is found surrounding the cell membrane in plant, algal and bacterial cells.
Plant cells have no cell wall?
No that is not true! All plant Cells and some microbes like bacteria have cell wall but no animal have cell wall.There are other cell organellis like chloroplast whcih are found only in plants but not in animals.
What is a outer supportive structure of a plant cell?
The cell wall is the outer supportive structure of a plant cell. It provides rigidity and support to the cell, helping the plant maintain its shape and structure. The cell wall is made up of cellulose, a complex carbohydrate that gives strength to the cell.
The main function of the cell wall is to provide support and protection?
True; plant cell
The structure and properties of the cell wall allow it to be selective and maintain homeostasis True or false?
True. The cell wall is selectively permeable, allowing only certain molecules to pass through, which helps maintain homeostasis by regulating what enters and exits the cell. Additionally, the cell wall provides structural support and protection for the cell.
True or false water carbon dioxide and oxygen can pass through the cell wall?
true
Is the sentence during cytokinesis in plant cells the new cell membrane forms before the new cell wall does true of false?
True
Is it true that animal cells have cell walls?
No, animal cells do not have cell walls. Instead, they are surrounded by a flexible membrane called the plasma membrane. Cell walls are found in plant cells, fungi, algae, and some bacteria, where they provide structural support and protection.
Is it true that Animal cells have a cell wall?
No, animal cells do not have a cell wall. Plant cells and some other organisms like fungi and bacteria have cell walls, but animal cells do not. Instead, animal cells have a cell membrane that surrounds and protects the cell.
Is it true that cell wall lies inside the cell membrane?
The cell membrane is the outer boundary in all cells that do not have a cell wall (such as animal cells). The cell wall is found surrounding the cell membrane in plant, algal and bacterial cells.
What protects the plants cell?
cell wall
Plant cells have no cell wall?
No that is not true! All plant Cells and some microbes like bacteria have cell wall but no animal have cell wall.There are other cell organellis like chloroplast whcih are found only in plants but not in animals.
Where is the cell wall located in an animal?
There is no cell wall in a animal cell but there is a cell wall in the plant cell.

Is this true both plants and animals cell can make food from sunlight?
I think yes bcuz of the cell wall Nd photosynthesise
