Lysosmes are not commonly found in plants. They are mostly found in animal-like eukaryotes. Lysosomes have digestive enzymes that breakdown molecules like proteins, carbohydrates and the like. They also breakdown worn out organelles. When broken down, they exit the lysosomes in vesicles so that the cell can expel it. This is why lysosomes are called the garbbage disposal of the cell.

Answer: No. You would not withdraw CSF if the needle is in the epidural space.
Explanation: There are 3 spaces that cover the spinal cord, which are epidural, subdural and subarachnoid spaces. The epidural space is the outer most space while the subarachnoid space is the inner most space. CSF flows from the brain where it is produced to the spinal cord. In the spinal cord it flows only in the subarachnoid space. Thus you would not be able to withdraw CSF if the needle is in the epidural space.
