They are called thylakoids.
Thylakoid.
Chloroplasts contain saclike photosynthetic membranes called thylakoids. The region outside the thylakoid membranes in the chloroplasts is called the stroma.
They are called grana.Light reaction takes place there.
Chloroplast is an organelle found in plants and algae cells where photosynthesis occurs. The chloroplast contains chlorophyll which is the light sensitive pigment that powers photosynthesis and other pigments. Chlorophyll gives the plant its green color A plastid containing chlorophyll, developed only in cells exposed to the light. Chloroplasts are minute flattened granules, usually occurring in great numbers in the cytoplasm near the cell wall, and consist of a colorless ground substance saturated with chlorophyll pigments. Under light of varying intensity they exhibit phototactic movements. In animals chloroplasts occur only in certain low forms. Chloroplasts are what give plants their green color. Organelle that makes sugars, using carbon dioxide, water, and the energy from sunlight. Cholorplasts can be found in plant cells and produces food. It is an eukariyotic organelle. It is important for photosynthesis
This is straight from www.thefreedictionary.com, so I get no credit at all:"Any of various invertebrate animals of the phylum Cnidaria, characterized by a radially symmetrical body with a saclike internal cavity, and including the jellyfishes, hydras, sea anemones, and corals. Also called coelenterate."
A medusoid is a Cnidarians:An invertebrate of the phylum Cnidaria (formerly Coelenterata)Coelenterates include the hydra, jellyfishes, sea anemones, and coralsThe medusoid is one of the 2 forms, the other is the polyp.having a saclike body with a single opening (mouth), which occurs in polyp and medusa forms.
Chloroplasts contain saclike photosynthetic membranes called thylakoids. The region outside the thylakoid membranes in the chloroplasts is called the stroma.
Light-independent reactions take place outside the thylakoids, in the stroma. The stroma is the fluid part of the chloroplast. The thylakoids are an abundance of saclike photosynthetic membranes.
They are called grana.Light reaction takes place there.

A cyst is an accumulation of fluid in a saclike cavity. A hydrocele is a collection of fluid in the scrotum.

Parasites such as tapeworm, planarian and live fluke have digestive systems that are saclike. Their digestive tracts have one opening and they live inside a host animal.
