Question

eukaryotes - animals, plants, fungi. eu - true nucleus. eukaryotic cells have more structures than prokaryotic cells. eukaryotes and prokaryotes both have a cell membrane, ribosomes, and dna. eukaryotes also have a nucleus! the dna in eukaryotic cells is found in the nucleus. eukaryotes also have organelles. organelles are structures that perform specific functions. these cells are found in animals, plants, and fungus. they can be unicellular or multicellular. eukaryotes are organisms made of one or more cells. they are unicellular or multicellular. every type of multicellular organism that exists is made up of eukaryotic cells. the only living organisms that are not eukaryotes are bacteria (they are prokaryotes). 8. where is dna found in a eukaryotic cell? __________ 9. how many cells are in eukaryotic organisms? ________ 10. what structures are found in both prokaryotes and all eukaryotes? c ________, d ________ study the eukaryotic plant and animal cells below. find the (a) cell membrane, the (b) nucleus, the (c) mitochondrion, the (d) ribosomes, the (e) chloroplast, the (f) cell wall and the (g) large vacuole list the plant cell structures: and their function a ________ b ________ c ________ d ________ e ________ f ________ g ________ list the animal cell structures: and their function a ________ b ________ c ________ d __________

Explanation:

1. The text states that in eukaryotic cells, DNA is found in the nucleus.
2. Eukaryotic organisms can be unicellular or multicellular, so the number of cells can vary from 1 to many.
3. Both prokaryotes and eukaryotes have a cell - membrane and ribosomes.

For plant cell structures and functions:

• A (Cell membrane): Controls the movement of substances in and out of the cell.
• B (Nucleus): Contains genetic material and controls cell activities.
• C (Mitochondrion): Produces energy through cellular respiration.
• D (Ribosomes): Site of protein synthesis.
• E (Chloroplast): Conducts photosynthesis.
• F (Cell wall): Provides support and protection.
• G (Large vacuole): Stores water, nutrients and waste products and helps maintain cell turgor.

For animal cell structures and functions:

• A (Cell membrane): Controls the movement of substances in and out of the cell.
• B (Nucleus): Contains genetic material and controls cell activities.
• C (Mitochondrion): Produces energy through cellular respiration.
• D (Ribosomes): Site of protein synthesis.

Answer:

1. In the nucleus.
2. Can be unicellular or multicellular.
3. Cell membrane, Ribosomes
