What else can I help you with?
How do the cells of nonvascular plants get the nutrients they need?
By diffusion of the nutrients through the cell walls and membranes.
Where do cell membranes live?
The cell membrane exists around the cell, keeping the contents inside and regulating the flow of nutrients and water to and from the cell
How do Unicellular organisms exchange gas eliminates wastes and absorbs nutrients?
directly through their cell membranes
Why the flow of energy through the biosphere depends on the cycling of nutrients?
doesnt
Do cell membranes make nutrients for cells?
Cell membranes do not make nutrients for cells. They are primarily responsible for controlling the entry and exit of substances into and out of the cell, as well as maintaining the cell's internal environment. Nutrients are typically obtained from the external environment through processes such as diffusion or active transport.
Does Mother's blood flows into the foetus through placenta.True or False?
False. The mothers blood flows through the placenta in vessels next to the foetal blood that flows in separate vessels. Oxygen and nutrients can flow from the mothers blood into the foetus' blood and carbon dioxide and waste products can flow from the foetus' blood to the mother's blood through the vessel membranes, however the two bloods will never actually mix.
Why are movements of energy and nutrients different through living systems?
nutrients flow in two directions , and energy recycles. By: val <3
The movements of energy and nutrients through living systems are different because why?

How multicellular organisms exchange materials?
Multicellular organisms exchange materials through mechanisms such as diffusion, active transport, and bulk flow. These processes occur through specialized structures like cell membranes, blood vessels, and respiratory or digestive systems, enabling the transport of gases, nutrients, and wastes throughout the organism's body.
What is apoplasmic and symplasmic nuturient movement?
Apoplasmic nutrient movement refers to the transport of substances through the apoplast, which is the network of cell walls and intercellular spaces, allowing nutrients to move without crossing cell membranes. In contrast, symplasmic nutrient movement occurs through the symplast, which consists of the cytoplasm of living cells connected by plasmodesmata, allowing nutrients to flow directly from cell to cell. Both pathways play crucial roles in the uptake and distribution of nutrients in plants.
Why cell membranes considered sei-permeable?
They're classified as semi permeable because it only allows certain enzymes and nutrients, etc, to get through.
How do cell membranes work to regulate the movement of substances in and out of cells?
Cell membranes are made up of a double layer of lipids with proteins embedded in them. These proteins act as channels and pumps that control the movement of substances in and out of the cell. The membrane is selectively permeable, allowing some substances to pass through while blocking others. This helps maintain the cell's internal environment and regulate the flow of nutrients and waste products.
