A digestive sac not related to other endomembrane structures
Peroxisomes.
Its structure is not derived from the ER In contrast to organelles of the endomembrane system, these organelles have at least two membranes separating the innermost space from the cytosol. Their membrane proteins aren't made by the endoplasmic reticulum, but by ribosomes in the cytoplasm and in the organelle itself.
These 2 systems are not related. They do not interact with each other.
These structures are absent in marine paramecium.Food vacuoles,which are round in shape,contain enzymes to digest the other smaller protozoans that paramecium feed on.
The more similar (or homologous) some chemical structures are, the more likely they are closely related. Conversely, greatly dissimilar structures indicate divergence a long time ago. If the only other clues about an organism are not specific enough, the chemical structures - and thereby other organisms - it is related to can be discerned by such a comparison.
No, planets do not have a digestive system. Digestive systems are biological structures found in living organisms that break down food to extract nutrients. Planets, being inanimate celestial bodies, do not possess biological functions or systems. They are composed of rocks, gases, and other materials, and do not engage in processes like digestion.
Something of, about or related to architecture.
The organelles that are a part of the endomembrane system include the endoplasmic reticulum, Golgi apparatus, lysosomes, vesicles, and the nuclear envelope. The endomembrane system is a network of membranous organelles within a eukaryotic cell that work together to transport proteins, lipids, and other molecules throughout the cell and to the cell membrane. It plays a key role in protein synthesis, processing, and trafficking within the cell.
Yes, grapevines are related to stem tendrils because grapevines use their tendrils, which are modified stem structures, to support themselves by wrapping around structures like trellises or other plants. Tendrils are specialized plant structures that help vines climb and support themselves.
The endomembrane system is extremely complex for being so miniscule. While there is no one element more important than any other, the vacuoles are an integral part of the system. These mini storage units are the keepers of both nutrients and waste from the entire cell.
The digestive system provides usable nutrients for the other systems.
It injects its digestive fluids into the body of its prey. It waits for the digestive fluids to disassemble the organic structures within the insect's exoskeleton and then sucks them back into its own digestive system. Some spiders have very powerful mouthparts that are capable of crushing the exoskeleton of insects and other prey. Those spiders chew their prey and exude digestive fluid into the chewed mass, and after that they absorb the digested fluid into their own digestive tract. The mouthparts of the black widow (and many other spiders) are too delicate to do anything more than get a little hole started in the exoskeleton.
