Acellular organisms - Study guides, Class notes & Summaries

AQA A LEVEL BIOLOGY Paper 1 2024 What is the function of the cell membrane? - ANS To control what enters and leaves the cell, acts as a barrier between the cell and its environment. What structural feature of the cell membrane allows substances to enter/leave? - ANS Partially permeable What is the fluid mosaic model? - ANS States that a membrane is a fluid structure (because phospholipids are constantly moving) with a "mosaic" of various proteins embedded in it Describe the...

archaea characteristics - Answer-has pseudopeptidoglycan in cell wall; S layer for cell wall (not exclusive); ether linked lipids in cell membrane (exclusive); has monolayer cell membrane sometimes (exclusive); rapid growth and divide by binary fission; metabolically diverse bacteria characteristics - Answer-has peptidoglycan in cell wall (exclusive); ester linked bilayer lipids in cell membrane (same as humans); rapid growth and divide by binary fission; metabolically diverse fungi charact...

Acellular organisms Viruses. Exist without a cellular structure. Cellular organisms Prokaryotes and Eukaryotes. Prokaryotes Organisms whose genetic material is not enclosed in membrane and lack specific organelles including a nucleus (bacteria). Eukaryotes Organisms whose genetic material is enclosed in nucleus (fungi, protozoa, algae). Prokaryotes versus Eukaryotes Prokaryotic cells are smaller than eukaryotic cells, and in addition to lacking a nucleus, they lack other complex interna...

1. What determines if a bacterial cell is Gram-positive or Gram-negative? Gram-negative bacteria are surrounded by a thin cell wall, while gram-positive bacteria lack a cell wall. 2. In this lab, both viruses and prions were introduced as acellular organisms. Do some research and describe one other type of acellular organism. What characteristics about this organism classify it as acellular? Another example of an acellular organism would be viroids. Viroids are small, single- stranded, cir...
