Answer:
Cell Wall and large central vacuole
Explanation:
All cells have a cytoskeleton and cell membrane, but cell walls and large central vacuoles are unique to plants. Cell walls give plants their rigid structure and the ability to withstand great force, while large central vacuoles provide a way for plants to store excess reacts or products derived from photosynthesis.
Answer:
undergo irreversible repression
Explanation:
Cellular differentiation refers to the process by which one cell and/or cell population divides and differentiates into more specialized cells. During cell fate differentiation, epigenetic marks modify chromatin structure in order to hamper the accessibility of the transcriptional machinery and transcriptional factors to different genes, which are irreversibly repressed. These epigenetic marks include DNA methylation and histone modifications (e.g., histone acetylation, histone methylation, etc). For example, it has been shown that DNA methylation and histone H3 lysine 27 tri‐methylation (H3K27me3) are epigenetic repressive marks on genomic regions that play a major role in gene expression programs during cell fate differentiation.
