Differentiate between meristematic and permanent tissues.​

Biology
1 answer:
Anna [14]3 years ago
3 0

Explanation:

The difference between Meristematic Tissue and Permanent Tissue are:

  • Meristematic tissue always has a prominent nucleus. Permanent tissue has a prominent nucleus in some like parenchyma while not in others like sclerenchyma.
  • Meristematic tissue has cells small in size and isodiametric in shape. Permanent tissue has cells large in size and their shape varies.

What are the Animal cells label?
LiRa [457]

Answer:Here they are.

Explanation:

Cell Membrane

   The thin layer of protein and fat that surrounds the cell. The cell membrane is semipermeable, allowing some substances to pass into the cell and blocking others.

Centrosome (Microtubule Organizing Center)

   A small body located near the nucleus - it has a dense center and radiating tubules. The centrosomes is where microtubules are made. During cell division (mitosis), the centrosome divides and the two parts move to opposite sides of the dividing cell. The centriole is the dense center of the centrosome.

Cytoplasm

   The jellylike material outside the cell nucleus in which the organelles are located.

Golgi body (Golgi Apparatus/Golgi Complex)

   A flattened, layered, sac-like organelle that looks like a stack of pancakes and is located near the nucleus. It produces the membranes that surround the lysosomes. The Golgi body packages proteins and carbohydrates into membrane-bound vesicles for “export” from the cell.

Lysosome (Cell Vesicles)

   Round organelles surrounded by a membrane and containing digestive enzymes. This is where the digestion of cell nutrients takes place.

Mitochondrion

   Spherical to rod-shaped organelles with a double membrane. The inner membrane is infolded many times, forming a series of projections (called cristae). The mitochondrion converts the energy stored in glucose into ATP (adenosine triphosphate) for the cell.

Nuclear Membrane

   The membrane that surrounds the nucleus.

Nucleolus

   An organelle within the nucleus - it is where ribosomal RNA is produced. Some cells have more than one nucleolus.

Nucleus

   Spherical body containing many organelles, including the nucleolus. The nucleus controls many of the functions of the cell (by controlling protein synthesis) and contains DNA (in chromosomes). The nucleus is surrounded by the nuclear membrane.

Ribosome

   Small organelles composed of RNA-rich cytoplasmic granules that are sites of protein synthesis.

Rough Endoplasmic Reticulum (Rough ER)

   A vast system of interconnected, membranous, infolded and convoluted sacks that are located in the cell’s cytoplasm (the ER is continuous with the outer nuclear membrane). Rough ER is covered with ribosomes that give it a rough appearance. Rough ER transports materials through the cell and produces proteins in sacks called cisternae (which are sent to the Golgi body, or inserted into the cell membrane).

Smooth Endoplasmic Reticulum (Smooth ER)

   A vast system of interconnected, membranous, infolded and convoluted tubes that are located in the cell’s cytoplasm (the ER is continuous with the outer nuclear membrane). The space within the ER is called the ER lumen. Smooth ER transports materials through the cell. It contains enzymes and produces and digests lipids (fats) and membrane proteins; smooth ER buds off from rough ER, moving the newly-made proteins and lipids to the Golgi body, lysosomes, and membranes.

Vacuole

   Fluid-filled, membrane-surrounded cavities inside a cell. The vacuole fills with food being digested and waste material that is on its way out of the cell.

nikdorinn [45]

The idea was that fertilizing the ocean and seas would lead to the in increase growth of phytoplankton population.


The oceanic plants do not release carbon dioxide into the air when they die because the sinks into the sea carrying with them the carbon dioxide for several centuries. This would then decrease the levels of carbon dioxide from the air as plants absorb carbon dioxide from the air during the process of photosynthesis.

Can any kind soul help me ASAP ​
Alinara [238K]

Answer:

9- C

cellulose strengthens the cell walls present in a plant

enzymes and antibodies are made of proteins

water is the universal solvent.

10- C, all 3

1- cytoplasm contains about 85% of water, which helps in movement within the cells.

2- urine contains 95% of water, and it dissolve urea and salts in it.

3- plasma contains 90% of water, so we can say that water allows transportation of substances in the blood.
