What else can I help you with?
What type of molecules cannot enter the cell?
polar molecules are repelled by the cells electrical charge.
How many sperm cells enter the plant ovule?
Plants do not have sperm cells. In plants, fertilization occurs when a pollen grain (containing sperm cells) lands on the stigma of a flower and grows a pollen tube to deliver the sperm cells to the ovule.
Does carbon dioxide molecules enter the Calvin from the atmosphere?
No, carbon dioxide molecules enter the Calvin cycle within the chloroplasts of plant cells. The stomata on the leaves allow carbon dioxide to diffuse into the leaf where it can be fixed into organic molecules during photosynthesis.
What part of the cell enters the cell and leaves?
The only things that enter and leave cells are molecules and proteins. organelles do not leave the cell.
Must sugar dissolve in blood to enter cells?
No, sugar enters cells through facilitative diffusion, a process that does not require it to dissolve in blood. Cells use specialized transport proteins to move sugar molecules from the blood into the cell.
What type of molecules cannot enter the cell?
polar molecules are repelled by the cells electrical charge.
What is a passive method by which glucose molecules enter cells?
Passive diffusion is a method by which glucose molecules enter cells. Glucose can diffuse through the cell membrane down its concentration gradient without the need for energy input from the cell.
Which of the following allows plants to be selective about the molecules that enter the xylem?
A waxy barrier in the plant root.The waxy barrier in the plant root prevents molecules that are in the cell walls from entering the xylem directly. To move into the xylem, molecules must first cross a plasma membrane and enter the cytoplasm of a root cell. This allows a plant to be selective about what enters the xylem.
What is the function of a cell selectively cells?
It allows some molecules to enter the cell and blocks entry to others

What are large protein molecules from its mother's milk that enter the cells lining the baby's digestive tract via?
endocytosis
Some hormones enter cells via?
Some hormones enter cells via membrane receptors that undergo conformational changes when the hormone binds to them. This binding activates intracellular signaling pathways that can lead to changes in gene transcription and ultimately influence cell function.
How do the nutrients that enter your cells compare with the food you eat?
Nutrients that enter your cells are broken down from the food you eat during digestion. The nutrients are then absorbed into the bloodstream and transported to cells for energy production, growth, repair, and maintenance. The cells use these nutrients to carry out their functions and support overall health.
What part of the cell enters the cell and leaves?
The only things that enter and leave cells are molecules and proteins. organelles do not leave the cell.
Must sugar dissolve in blood to enter cells?
No, sugar enters cells through facilitative diffusion, a process that does not require it to dissolve in blood. Cells use specialized transport proteins to move sugar molecules from the blood into the cell.
What must the molecules in a capillary enter before they enter the cell?
Molecules traveling within the bloodstream pass through the capillary cell wall via osmotic pressure and diffuse through the interstitial fluid before encountering the tissue cell wall.
