Science Lent 1

• The part of the plant important for reproduction is the root, which is necessary for mineral absorption.
• The cell found in the root of plants and necessary for mineral absorption is the root hair cell.
• The other purpose of the roots is to anchor the plant in the soil.
• Chloroplasts are found in the leaves of plants, where they perform photosynthesis.
• The role of the chloroplast is to produce energy through photosynthesis.
• The male sex cell of a plant is called the pollen grain.
• The part of the flower that receives pollen is the stigma.
• Seed dispersal is important to plants as it allows them to spread their genes to new areas.
• Insects and spiders are different types of arthropods, with insects having three body parts, six legs, and often having wings, while spiders have two body parts, eight legs, and no wings or antennae.
• Design an insect or an arachnid with an adaptation which makes it unique and well suited for its environment.
• Write an ‘Attenborough-style’ script about how your arthropod lives, eats and survives.
• The horsefly is an insect.
• Female horseflies bite horses and feed on their blood, while male horseflies feed on plants.
• Insects have three body parts, six legs, and often have wings.
• All spiders have a poisonous bite, but only some cause harm.
• Spiders can build structures with silk to help them capture prey.
• Spiders have two body parts, eight legs, and no wings or antennae.
• An invertebrate does not have a backbone.
• Apart from a spider, another arachnid is a camouflage specialist.
• The eyes, mouth and antennae of insects are carried in the head, while the thorax carries three pairs of jointed legs and usually two pairs of wings, and the abdomen contains the stomach, breathing tubes and reproductive organs.
• Camouflage is the ability to blend in with the surroundings.
• An insect's adaptation helps it survive.
• All insects have a hard exoskeleton made of chitin, and roughly 8 out of 10 animal on earth are insects.
• Variation makes the world a beautiful place.
• Characteristics are features of an organism, which can be something we can see (like hair colour) or something we can’t see (like blood group).
• Variation is the difference in our characteristics.
• Children inherit characteristics from their parents, each inheriting a different combination of characteristics, this is called inherited variation.
• Other characteristics are affected by a person’s surroundings, this is called environmental variation.
• Gareth measured the heights of the 16-year-old pupils at his school and recorded the distribution in a bar chart.
• Natural hair colour is an example of an inherited trait.
• Environmental factors can influence the expression of inherited traits, such as the ability to write, weight, hair colour, and height.
• Genetic (inherited) variation can be both environmental and inherited.
• Gareth, a 16-year-old pupil, described himself as a boy, weighing 600 N, being 1.8 m tall, speaking French, having brown eyes, and having a scar on his chin.
• Some variation is continuous, meaning it may have any one of a large range of values, such as height.
• Some variation is discontinuous, meaning it can only have one of a fixed number of options, such as eye colour.
• Gareth also collected data about the features in the list below.
• Environmental variation can be influenced by factors such as blood type, tattoos, piercings, inherited diseases, shoe size, intelligence, artistic ability, food intolerances, ability to sing, athletic ability, nail length, height, natural eye colour, playing an instrument, ability to read, shape of ear lobes, skin colour, hair length, and illness.
• Brown eyes, being a boy, 1.8m tall, 600N, height, weight, speaking French, and having brown eyes would show a similarly shaped distribution to Gareth’s bar chart.
• There are two images with differences that can be found.
• Scientific questioning involves understanding the parts of plant and animal cells, describing differences between bacteria, Amoeba and Euglena cells, explaining how single-celled organisms are adapted, and discussing how single-celled organisms are adapted for life.
