What else can I help you with?
Are cells in pencil shavings alive why or why not?
No, cells in pencil shavings are not alive because they come from dead plant material that has been processed to create the pencil. Once the cells are removed from the living plant, they can no longer carry out functions of a living cell.
What accounts for an animal cell's less rigid shape compared to plant cells?
Animal cells lack a cell wall, present in plant cells, which provides rigidity and shape. Instead, animal cells have a flexible plasma membrane that allows for more dynamic changes in shape. Additionally, animal cells have a more varied cytoskeleton that provides support while allowing for movement and shape changes.
Where does nitrogen from atmosphere go before it enters a plant?
The nitrogen goes into the nodules of the plant.
How does a plant that lacks nitrogen look?
Deficiency of nitrogen gives pale yellow color to the plant
What changes energy into food in plant cells?
Photosynthesis is the process by which plant cells convert light energy into chemical energy in the form of glucose (food). This process occurs in the chloroplasts of plant cells, where chlorophyll absorbs light energy, which is then used to convert carbon dioxide and water into glucose and oxygen.
What is the process that cause changes in plant an animal cells?
Mutations cause changes in plant an animal cells.
Plant cells that absorb water and nitrogen compounds?
Root cells are primarily responsible for absorbing water from the soil through their root hairs. Nitrogen is absorbed by plant cells through specialized structures called root nodules, which contain nitrogen-fixing bacteria that convert atmospheric nitrogen into a usable form for the plant. These cells work together to ensure plants have the necessary resources for growth and development.
In order to make proteins plant cells need nitrogen. In what form do they absorb nitrogen from the soil?
Plant cells absorb nitrogen from the soil in the form of nitrate (NO3-) or ammonium (NH4+). These forms of nitrogen are taken up by the plant roots and then transported to different parts of the plant for protein synthesis and other essential physiological processes.
Give the name of the type of plant cell that absorbs water and nitrogen?
Root hair cells are the type of plant cell that absorbs water and nitrogen from the soil. These cells are found along the surface of the plant root and have a large surface area to increase absorption efficiency.
What kind of nitrogen do plants need?
Bacteria and plant roots perform nitrogen fixation, which allows plants to use the nitrogen. Nitrogen is used in cells to build proteins and DNA. However, plants get their nitrogen as "nutrients" in the soil.
Are cells in pencil shavings alive why or why not?
No, cells in pencil shavings are not alive because they come from dead plant material that has been processed to create the pencil. Once the cells are removed from the living plant, they can no longer carry out functions of a living cell.
What is a process that changes the nature of cells?
When the plant eats. This changes the plant cells because, when the plant eats it absorbs what it eats which is water, if you were to look at a picture of a plant cell with water in it after the plant "eats" the water the plant cell looks like it has less liquid in it.
Are proteins present plant cells?
Plants can store proteins in embryo and vegetative cells. It is used to provide carbon, nitrogen, and sulfur resources for growth and development.
OBSERVING OSMOSIS IN PLANT CELLS?
You can observe osmosis in plant cells by placing a plant cell in a hypertonic or hypotonic solution and observing any changes in cell size and shape due to the movement of water. Hypertonic solution will cause cell to shrink (plasmolysis) and hypotonic solution will cause cell to swell. You can use a microscope to observe these changes in plant cells during osmosis.
Why is nitrogen important to plant and animals?
because the nitrogen helps the plant grow
What accounts for an animal cell's less rigid shape compared to plant cells?
Animal cells lack a cell wall, present in plant cells, which provides rigidity and shape. Instead, animal cells have a flexible plasma membrane that allows for more dynamic changes in shape. Additionally, animal cells have a more varied cytoskeleton that provides support while allowing for movement and shape changes.
Chloroplasts are found in what types of cells?
Plant cells, not animal cells.
