How do the structures and arrangement of cells in an onion help to protect and support the parts underneath it?
The outermost layer of cells in an onion, the epidermis, forms a protective barrier against environmental stresses. The arrangement of cells in multiple layers allows for strength and flexibility, providing support to the parts underneath. Additionally, specialized cells called sclerenchyma cells provide extra structural support to the onion.
What are examples of ground tissue?
Examples of ground tissue in plants include parenchyma, collenchyma, and sclerenchyma cells. Parenchyma cells are the most common and versatile, responsible for storage, photosynthesis, and support. Collenchyma cells provide flexible support for growing plant parts, while sclerenchyma cells provide rigid, structural support.
Plant cells provide structural support and have cell walls thickened at the corners are called?
Collenchyma cells.These cells support the plant without restraining growth, they are more flexable. They only have a primary wall that is thickest at the corners and made of hemicellulose (made of shorter chains of glucose than cellulose).
What are the special features of collenchyma cells?
Collenchyma cells provide structural support to young plant parts, such as stems and petioles, due to thickened cell walls. These cells have a flexible and elongated shape that allows them to stretch as the plant grows. Collenchyma cells also have living protoplasts that can provide metabolic support to the plant.
What three items are functions of astrocytes?
The astrocytes provide structural support, join parts, and assist in the regulation of concentrations of nutrients and ions. Oligodendrocytes provide insulation (myelin) around axons. Microglia support neurons phagocytize bacterial cells and debris. They also form scars in dammaged areas. Ependymal cells cover specialized brain parts and make up the inner linings that surround spaces in the brain and spinal cord.

What are 3 types of plant cells?
The three types of plant cells are parenchyma cells, collenchyma cells, and sclerenchyma cells. Parenchyma cells are the most common and versatile, involved in photosynthesis and storage. Collenchyma cells provide support to growing plant parts. Sclerenchyma cells are rigid and provide structural support to mature plant parts.
A plant cell has two parts that animal cells do not have they are the?
These parts are the cell wall (animal cells just have a cell membrane) and the vacuole. Plants also have chloroplasts which animal cells do not have.
What is the function of the sclerenchyma cells?
Sclerenchyma forms the support system in plants. They also help in transport of water. They are made up of two different types of cells - sclereids and fibers. Sclereids - they are irregular in shape and the walls are thick, hard and lignified. They give the woody structure to plants for protection and support. Fibres - they are elongated, needle shaped cells with small lumen. They also have small pits or openings. They help in the transport of water to the different parts of the plant. Starch granules are stored in the young and living plants.

What is the function of collenchyma?
Collenchyma cells have strong, flexible cell walls the help support larger plants. Collenchyma cells make up the familiar "strings" of a stalk of celery.Collenchyma cells help support young parts of the plant shoot. They provide flexible support without restraining growth and they elongate the stems and leaves they support.

What is the function of neuroglial cells in nervous tissue?
Glial cells provide protection and support for the neurons. This is why they are called "the supporting cells" of the nervous system. They act as insulation and provide structure to surrounding neurons. Some protect the neurons from disease. Some can provide the insulation (white matter) along their axons, through differing mechanisms depending on the types. Astrocytes help regulate chemical environment and blood flow, schwann cells provide myelin sheaths (insulation) in the PNS, oligodendrocytes provide myelin sheaths in the CNS, and microglia act similarly to certain white blood cells.
Which body parts provide the effort when bones act like levers?
The muscles would provide the extra effort because the muscles are like extra foundations moving your body around.
