Animal cells each have a centrosome and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, whereas animal cells do not.

Answer:
Chloroplast -----membranes----------internal
---------external
----- Tylacoids-------------Grana
----- Stroma
You will find the complete concept map in the attached files
Explanation:
Chloroplasts are composed of three membrane systems. Surrounding the organelle we can find the external membrane. To the interior of the organelle, there is the internal membrane. These two systems are separated by the intermembrane space. According to the endosymbiotic theory, the presence of a double membrane is the characteristic that reinforces the idea of a prokaryote being phagocyted by a eukaryote. The internal membrane looks identical to the membrane of bacterias, while the external membrane looks like the eukaryotic one.
Thylakoids are located in the interior of the organelle. These structures are also surrounded by a membrane, and in their interior, there is the thylakoid space. Each thylakoid looks like a hollow sac, and together with other thylakoids, they form piles, known as grana. Different piles or grana connect to each other by longer membranes. These internal structures together compose the third system of membranes. The photosynthetic pigments are located in the thylakoids, where it occurs the light-dependent reactions.
Surrounding the thylakoids there is a dense liquid called the stroma. Here takes a place the Calvin cycle.
Answer:
Virus enters into the host cell through a process called endocytosis.
Explanation:
Endocytosis is a process in which molecule enters into the cell through cell membrane. Virus also enter into the host cell through this process. After entering, the virus starts replication and grow in numbers inside the host cell and take nutrients from it which is used in the process of reproduction. When virus population increases, it cause infection to the neighboring cells.
Relative dating is used to arrange geological events and the rocks are left behind the sequence. Stratigraphy is the method of reading the order.
Explanation:
The Relative dating do not provide actual numerical dates for the rocks. The principle states that in an undisturbed sequence of sediments layers are increased in age from the top to bottom.
The difference between relative and absolute dating is the relative age is age of a rock layer when compared to other layer and Absolute age is the numeric age of layer of rocks or fossils and it is determined by using radiometric dating.
The relative dating techniques are used for climate chronology, dendrochronology, ice core sampling, stratigraphy, and seriation.
