Little sacs that carry molecules are known as vesicles.
Exocytosis is the process by which cells secrete products such as hormones, enzymes, or neurotransmitters. During exocytosis, vesicles containing the cell products merge with the cell membrane and release their contents outside of the cell. This allows cells to communicate with other cells and regulate various biological processes.
Cells produce ammonia and urea as waste products containing nitrogen when they break down proteins. These waste products are subsequently excreted by the body through processes such as urination and sweating.
Yes, the process of exocytosis does require energy. During exocytosis, vesicles containing molecules are transported to the cell membrane and released outside the cell. This process requires energy in the form of ATP to power the movement of the vesicles and the fusion of the vesicle membrane with the cell membrane.
Tears and saliva are products released by cells using exocytosis. This process involves the fusion of a vesicle containing the product with the cell membrane, releasing the contents outside the cell.
A cell that releases exosomes, which are small vesicles containing cell fragments and proteins, is an example of a secretion that contains cell fragments. Exosomes play roles in cell communication and the transfer of biomolecules between cells.
Small sacs containing cell products that can be transported in the cell is Vesicle

Well if the cell is to grow it needs food to come in and wast products to go out.
endocytosis
A small vessel or vesicle inside a cell containing enzymes is called a lysosome.
How red blood cell are suitable for carrying out their functions
The organelle that packages and stores proteins is the Golgi apparatus. It produces vesicles containing proteins that are ready to be transported to other parts of the cell or secreted outside the cell.
Exocytosis is the process by which cells secrete products such as hormones, enzymes, or neurotransmitters. During exocytosis, vesicles containing the cell products merge with the cell membrane and release their contents outside of the cell. This allows cells to communicate with other cells and regulate various biological processes.
Active transport is important for cell function as, various activities keep taking place such as manufacture of protein, fat, etc. For all these activities raw materials are needed which need to be transported to the various cell organelles. Also, the waste products too need to be transported out of the cell body.
Blood is a transport fluid. It mainly transports oxygenated blood (blood containing oxygen) from the heart around the body to every cell. Carbon dioxide, which is a waste produced in cellular respiration, is removed from the cell into the blood, and replaced with oxygen. The carbon dioxide is then transported in deoxygenated blood (blood containing carbon dioxide) towards the heart and lungs (through veins) to be expelled from the body. So basically, blood must be delivered to cells in the body to supply oxygen for cellular activities, supply essential nutrients to the cell, and remove waste products (such as carbon dioxide) from the cell.
