GCSE Biology Paper 1 Exam Questions
With Highly Rated Answers
What are Eukaryotic and Prokaryotic cells? - ANSEukaryoteic cells are complex, these include plant
and animal cells.
Prokatyotic cells are smaller and simpler, e.g bacteria
In a cell, what is cytoplasm? - ANSCytoplasm is a gel like substance where most chemical reactions
happen.
What is the difference between a cell membrane and a cell wall? - ANSA cell membrane holds the
cell together and controls what goes in and out of the cell. Where as, a cell wall is made of cellulose
and supports and strengthens the cell
what do ribsomes do? - ANSThey are involved in translation of genetic material in the synthesis of
proteins
Where are chloroplasts found and what is their main function? - ANSChloroplasts are found in plant
cells. This is where photosynthesis happens, so their job is to make food for the plant
In a bacterium, what controls the cell's activities and replication? - ANSChromosomal DNA
An egg/sperm cell is a ___?___ nucleus - ANSAn egg/sperm cell is a HAPLOID nucleus
In a sperm cell, where and why is there an acrosome? - ANSAn acrosome is found at the front of the
"head", where it stores enzymes needed to digest its way through the membrane of the egg cell
In an ciliated epithelial cells, what is the function of the cilia? - ANSTo move substances in one
direction, along the surface of the tissue
microscopes use lenses to.... - ANSMagnify images/ increase the resolution of an image
