What are 3 similarities between prokaryotic and eukaryotic cells?
Simple, primitive cells are prokaryotic; they have no nucleus and no organelles encased in plasma membranes. Three similarities between prokaryotic and eukaryotic cells are that both have vesicles, vacuoles, and the ability to carry out the eight functions of life.
What are the major differences between prokaryotic and eukaryotic cells?
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information.
What are the similarities and differences between prokaryotic and eukaryotic genomes?
Prokaryotes are typically haploid, usually having a single circular chromosome found in the nucleoid. Eukaryotes are diploid; DNA is organized into multiple linear chromosomes found in the nucleus. Supercoiling and DNA packaging using DNA binding proteins allows lengthy molecules to fit inside a cell.
What are 2 types of eukaryotic cells?
Eukaryotic cells may be classified into two groups based on the number of cells that make an individual organism: (1) unicellular eukaryotic cells and (2) multicellular eukaryotic cells.
Which came first prokaryotes or eukaryotes?
The oldest prokaryotic fossils are 3.5 billion years old, while the oldest eukaryotes are relative newcomers, having fossilized for the first time a mere 1.5 billion years ago.
What 2 structures do plants have that animal cells do not?
The plant cell has a cell wall, chloroplasts, plastids, and a central vacuole—structures not found in animal cells.
What are the two main differences between plants and animals?
Differences between plants and animals: Locomotion: Plants generally are rooted in one place and do not move on their own (locomotion), whereas most animals have the ability to move fairly freely. Photosynthesis: Plants contain chlorophyll and can make their own food, this is called Photosynthesis.
Do trees feel pain cutting?
The simple answer is that, currently, no one is sure whether plants can feel pain. We do know that they can feel sensations. But plants don’t have that ability—nor do they have nervous systems or brains—so they may have no biological need to feel pain.
