It looks like you're working on a biology exam related to cell structures and their functions. Here’s a breakdown of the structures you mentioned, along with their names and functions:
-
V - Mitochondrion: This structure is responsible for producing energy for the cell through cellular respiration.
-
U - Golgi apparatus: Its function is to package and sort proteins before they are sent to their destinations within or outside the cell.
-
X - Cell membrane: This structure controls what enters and exits the cell, maintaining the internal environment.
-
Nucleus: The nucleus holds the genetic instructions (DNA) for the cell, which directs all cellular activities.
To summarize:
- V → Mitochondrion (energy production)
- U → Golgi apparatus (packaging and sorting proteins)
- X → Cell membrane (controls entry/exit of substances)
- Nucleus → (holds instructions for the cell’s activities)
