Saclike structure that stores materials for use by the cell?
Vacuole is the saclike structure within a cell that stores materials such as water, nutrients, and waste products for use by the cell. Vacuoles help maintain the cell's shape, regulate its internal environment, and facilitate processes like digestion and waste removal.
May be involved in the transport of substances within a neuron?
Neurofibrils
What does a vesicle look like?
A small spherical phospholipid bilayer (for polar substances) or monolayer (for hydrophobic substances). They also have embedded, enclosing or attached proteins for targeting, structure and transport.
How are substances and structures transported within the cell?
Substances and structures are transported within the cell through processes such as diffusion, facilitated diffusion, active transport, and vesicular transport. Diffusion involves the movement of molecules from an area of high concentration to low concentration. Facilitated diffusion uses protein channels to help substances across the cell membrane. Active transport requires energy to move molecules against their concentration gradient. Vesicular transport involves the formation of vesicles that transport substances within or out of the cell.
What is the duct of a lumen?
The duct of a lumen is a passageway that allows substances to flow through a hollow structure, such as in the case of the digestive or excretory systems. The lumen refers to the central space within a tube or vessel where substances pass through. Collectively, the duct and lumen work together to transport materials within the body.
What is the process by which substances enter and leave cells and become distributed within cells?
Substances enter and leave cells through processes such as diffusion, facilitated diffusion, active transport, and endocytosis/exocytosis. Once inside the cell, substances can become distributed within cells through diffusion, cytoplasmic streaming, vesicular transport, and interactions with organelles.
What is the type of transport in which a cell goes against the concentration gradient in order to diffuse substances within?
Active transport is the type of transport in which a cell moves substances against their concentration gradient, requiring energy to do so. This process helps maintain the internal balance of substances within the cell.
What substances used to help active transport occur within cells?
Proteins are major substances involved in active transport within cells. Examples include ion pumps like Na+/K+ ATPase and transporters like glucose transporters. ATP provides the energy needed for these proteins to actively transport molecules across the cell membrane.
Why are callipares 1 cell thick?
Callipares are one cell thick to facilitate the exchange of gases, nutrients, and waste products with the surrounding environment through diffusion. This simple structure allows for efficient transport of substances within the organism.
What does the endoplasmic reticulum have?
Endoplasmic reticulum is a network of tube like structures. It helps in the transport of substances within the cell.
A small sac like structure used to transport substances within the cell?
A vesicle is a small sac-like structure that transports substances within the cell. Vesicles can contain a variety of molecules and assist in processes such as transporting proteins, lipids, and other cellular components between different parts of the cell. They play a crucial role in maintaining cellular function and organization.
Do flowering plants transport substances through tissue?
Flowering plants use both xylem and phloem tissues to transport water and food products within the plant
