All the remaining structures are virtually identical to those found in animal cells ribosomes synthesize proteins and are found at tached to the endoplasmic reticulum and free in the cytoplasm mitochondria provide energy by oxidizing the carbohydrate made in the chloroplasts microtubules and microfilaments seem to provide support and produce movement lysosomes and microbodies contain enzymes and the apparently structureless fluid making up the rest of the cytoplasm is called the hyaloplasm.
