Question

plant cells have cell walls and chloroplasts. plant cells have two parts that animal cells do not have. plant cells have cell walls and chloroplasts. cell walls the cell wall is a strong, rigid layer that protects, supports, and shapes the plant cell. it surrounds the cell membrane. some cell walls are very thick, such as those in a tree. when joined with others, they can support a very large plant. some cell walls are thinner, like those in celery. chloroplasts chloroplasts carry out photosynthesis that stores energy from sunlight as chemical energy for the plant. the chloro - part of the name chloroplast means “green.” chloroplasts contain chlorophyll, a green pigment, that helps capture energy from sunlight. like mitochondria, chloroplasts have two membranes and their own ribosomes and dna. circle the organelle that is similar in structure to mitochondria. 3.2 vocabulary check cytoskeleton golgi apparatus lysosome nucleus vesicle centriole endoplasmic reticulum mitochondrion cell wall ribosome vacuole chloroplast mark it up go back and highlight each sentence that has a vocabulary word in bold. choose the correct term from the list for each description. 1. little sacs that carry molecules __ 2. bumps that link amino acids 3. green organelles for photosynthesis 4. the skeleton of the cell 5. bean - shaped energy supplier 6. holder and protector of dna 3.2 the big picture 7. what do the nucleus, er, ribosomes, golgi apparatus, and vesicles work together to do? 8. how are plant cells different from animals cells? __

Explanation:

1. Vesicles are little sacs that carry molecules.
2. Ribosomes link amino - acids.
3. Chloroplasts are green organelles for photosynthesis.
4. Cytoskeleton is the skeleton of the cell.
5. Mitochondrion is a bean - shaped energy supplier.
6. Nucleus is the holder and protector of DNA.
7. These organelles work together to make and transport proteins. The nucleus contains DNA which has the instructions for making proteins. Ribosomes make the proteins, the endoplasmic reticulum (ER) modifies and transports them, the Golgi apparatus further modifies, sorts and packages them, and vesicles transport the finished proteins to their destinations.
8. Plant cells have cell walls and chloroplasts, which animal cells do not have. Cell walls provide protection, support and shape to plant cells, and chloroplasts carry out photosynthesis to store energy from sunlight as chemical energy for the plant.

Answer:

1. vesicle
2. ribosome
3. chloroplast
4. cytoskeleton
5. mitochondrion
6. nucleus
7. Make and transport proteins
8. Plant cells have cell walls and chloroplasts; animal cells do not.
