The endomembrane system consists of the nuclear envelope, ER, Golgi apparatus, lysosomes, vesicles, and plasma membrane. They collaborate to transport, package, and alter proteins and lipids. Components like mitochondria or chloroplasts are not part of the endomembrane system.
The endomembrane system in eukaryotic cells is composed of the nuclear envelope, the endoplasmic reticulum (ER), Golgi apparatus, lysosomes, vesicles, and the plasma membrane. These cellular components work together to perform several functions. Notably, they modify, package, tag, and transport proteins and lipids that form the membranes.
Starting with the nuclear envelope, it protects the contents of the nucleus by separating it from the cytoplasm. The endoplasmic reticulum synthesizes proteins and lipids. Golgi apparatus serves to further modify, sort, and package these proteins and lipids for transportation. lysosomes are involved in breaking down waste materials and cellular debris in the cell. Vesicles transport molecules around the cell. Finally, the plasma membrane controls the movement of substances in and out of the cell.
The endomembrane system does not include organelles like mitochondria or chloroplasts, as their membranes are not part of this system.

Answer:
an objective summary of an article on plant and animal reproduction, it would be important to include key information such as:
1. Overview of plant and animal reproduction processes: Provide a general description of how plants and animals reproduce, including the different mechanisms and strategies involved.
2. Importance of reproduction for species survival: Highlight the significance of reproduction in ensuring the continuation and survival of plant and animal species.
3. Key factors influencing plant and animal reproduction: Discuss the various factors that can impact plant and animal reproduction, such as environmental conditions, mating behaviors, pollination, seed dispersal, and reproductive strategies.
4. Reproductive adaptations and diversity: Explore the diverse range of reproductive adaptations and strategies found in different plant and animal species, showcasing the remarkable variety of reproductive mechanisms in nature.
5. Implications for conservation and management: Address the relevance of understanding plant and animal reproduction for conservation efforts, ecosystem management, and addressing issues related to declining populations or endangered species.
Remember, the specific statements to include in an objective summary would depend on the content and focus of the article you are summarizing.
