What else can I help you with?
What cells do animals have that plants dont?
Animals have specialized cells such as nerve cells, muscle cells, and blood cells that are not found in plants. These cells are responsible for functions like movement, coordination, and transportation of nutrients and oxygen throughout the body.
Which cell junction will allow the movement of molecules between two plant cells?
Plasmodesmata is the cell junction in plant cells that allows the movement of molecules between adjacent cells. These junctions are channels that pass through the cell walls of plant cells, facilitating the transport of water, nutrients, and signaling molecules between neighboring cells.
Osmosis is important to cells because?
Osmosis is important to cells because it allows for the movement of water and nutrients into and out of the cell. This process helps cells maintain proper hydration and internal balance, which is essential for their survival and functioning.
What are the differences between apoplast and symplast in plant cells and how do they contribute to the movement of water and nutrients within the plant?
Apoplast and symplast are two pathways for water and nutrient movement in plant cells. The apoplast is the space outside the cell membrane, including cell walls and intercellular spaces, while the symplast is the interconnected network of living cells through plasmodesmata. Water and nutrients can move through the apoplast by following a continuous path through the cell walls and spaces between cells. In contrast, the symplast allows for movement through the living cells themselves via plasmodesmata, which are channels that connect the cytoplasm of adjacent cells. The apoplast pathway is faster but less selective, while the symplast pathway is slower but more controlled. Both pathways work together to efficiently transport water and nutrients throughout the plant, with the apoplast facilitating rapid movement and the symplast ensuring regulation and selectivity.
What carries nutrients to the body's cells?
The bloodstream carries nutrients to the body's cells. Nutrients from the food we eat are absorbed in the digestive system and then transported via the bloodstream to cells throughout the body, providing them with the necessary energy and building blocks for proper functioning.
What is the most important of the blood?
The blood's most important job is the movement of wastes, oxygen, and nutrients to and from body cells. This movement allows the cells to maintain cellular homeostasis.
Where does nutrients enters the blood?
Nutrients are absorbed by the blood vessel in the small intestines. Special cells in the small intestines are facilitate this movement.
What is the most important job of the blood?
The blood's most important job is the movement of wastes, oxygen, and nutrients to and from body cells. This movement allows the cells to maintain cellular homeostasis.
What cells do animals have that plants dont?
Animals have specialized cells such as nerve cells, muscle cells, and blood cells that are not found in plants. These cells are responsible for functions like movement, coordination, and transportation of nutrients and oxygen throughout the body.
What happens when cells are given nutrients?
When cells are given nutrients, they metabolize them, and grow and divide to create more cells. If they are not given nutrients, they die.
Which cell junction will allow the movement of molecules between two plant cells?
Plasmodesmata is the cell junction in plant cells that allows the movement of molecules between adjacent cells. These junctions are channels that pass through the cell walls of plant cells, facilitating the transport of water, nutrients, and signaling molecules between neighboring cells.
Does water carry nutrients to cells?
Yes, water plays a crucial role in transporting nutrients to cells. It acts as a solvent, dissolving essential nutrients and facilitating their movement through the bloodstream. Additionally, water helps maintain cell structure and function, allowing for efficient nutrient uptake and waste removal. Without adequate hydration, nutrient delivery to cells can be compromised.
How nutrients are used by cells?
Nutrients are used by the body's cells as a source of energy
Do all cells assimilate nutrients?
The assimilation of nutrients refers to how cells use energy. Not all cells assimilate nutrients because some are not active.
Does onion cells have intercellular space between them?
Yes, onion cells do have intercellular space between them. These spaces allow for the movement of substances such as nutrients and gases within the onion tissue.
Describe how nutrients are used by cells?
Nutrients are used by the body's cells as a source of energy
Osmosis is important to cells because?
Osmosis is important to cells because it allows for the movement of water and nutrients into and out of the cell. This process helps cells maintain proper hydration and internal balance, which is essential for their survival and functioning.
